1 00:00:00,920 --> 00:00:04,080 Speaker 1: Welcome to you stuff you should know from house stuff 2 00:00:04,080 --> 00:00:12,400 Speaker 1: Works dot com. Hey, and welcome to the podcast. I'm 3 00:00:12,480 --> 00:00:16,360 Speaker 1: Josh Clark and they're sitting by me. Is Chuck Bryant 4 00:00:16,560 --> 00:00:23,200 Speaker 1: across from you and Jerry Rowland beside us. Here we are, Yeah, 5 00:00:23,440 --> 00:00:26,920 Speaker 1: this is stuff. Hey, and this is a fan request 6 00:00:28,560 --> 00:00:32,920 Speaker 1: by one of our younger fans. Yeah. When Cormack ron Dalzo, 7 00:00:33,000 --> 00:00:36,120 Speaker 1: it's right, our buddy, Joe's son and wife Cat, they 8 00:00:36,120 --> 00:00:40,680 Speaker 1: all listen as a family and it's adorable. They shout 9 00:00:40,800 --> 00:00:44,040 Speaker 1: at their stereo as a family. Yeah, apparently Cat shouted 10 00:00:44,080 --> 00:00:47,080 Speaker 1: at the stereo when you didn't remember thirteen year old 11 00:00:47,080 --> 00:00:51,159 Speaker 1: girls doing finger spelling sign language, Joe said. Kat was like, 12 00:00:51,400 --> 00:00:53,760 Speaker 1: how can he not have known this? That's all we did. 13 00:00:54,520 --> 00:00:58,680 Speaker 1: It wasn't around Tolito. Yeah, and you know what, Emily 14 00:00:58,720 --> 00:01:00,440 Speaker 1: didn't know about it either, and she was in Ohio, 15 00:01:00,480 --> 00:01:04,760 Speaker 1: so maybe it's everywhere but Ohio, Ohio. Colon left behind 16 00:01:04,800 --> 00:01:09,360 Speaker 1: as usual. It's pretty funny. But yeah, Cormack suggested that 17 00:01:09,400 --> 00:01:12,760 Speaker 1: we do an episode on black box flight recorders, and 18 00:01:12,800 --> 00:01:15,880 Speaker 1: that's what we're doing. Yeah, So Chuck, if you'll indulge 19 00:01:15,920 --> 00:01:19,160 Speaker 1: me before we get started. Um, I don't know if 20 00:01:19,160 --> 00:01:22,120 Speaker 1: you remember, but a couple of years ago a fan 21 00:01:22,240 --> 00:01:26,160 Speaker 1: sent in some day planners for us UM that were 22 00:01:26,200 --> 00:01:28,800 Speaker 1: like year long day planners, the the ones made out 23 00:01:28,800 --> 00:01:31,360 Speaker 1: of old library books. Yeah, and like um and they 24 00:01:31,400 --> 00:01:36,520 Speaker 1: had like h like de coupage like clicker stuff on 25 00:01:36,680 --> 00:01:40,440 Speaker 1: the on the cover. They were great. Perfect. Can't find 26 00:01:40,480 --> 00:01:44,520 Speaker 1: anything even remotely that good anywhere I've been looking for 27 00:01:44,560 --> 00:01:48,000 Speaker 1: a while. So, dear listener, if you're still out there 28 00:01:48,000 --> 00:01:50,400 Speaker 1: and you were listening UM, get in touch with us, 29 00:01:50,400 --> 00:01:52,560 Speaker 1: because I would love to buy those from you every year. 30 00:01:52,840 --> 00:01:55,240 Speaker 1: Oh yeah, you like those? Oh they were great? Yeah? Yeah, 31 00:01:55,280 --> 00:01:58,160 Speaker 1: you mean went crazy for it. Yeah, So if you 32 00:01:59,040 --> 00:02:02,680 Speaker 1: are that person, get in touch with us. Yeah. Stuff 33 00:02:02,720 --> 00:02:05,760 Speaker 1: podcast at Discovery dot com and put in the subject 34 00:02:05,760 --> 00:02:10,840 Speaker 1: line I'm the person Josh is looking for our day planners. 35 00:02:11,840 --> 00:02:15,880 Speaker 1: Uh okay, thank you, Chuck. So we're talking black boxes, 36 00:02:16,080 --> 00:02:18,440 Speaker 1: that's right, it's pretty interesting. I thought, Yeah, we should 37 00:02:18,480 --> 00:02:21,000 Speaker 1: probably put to rest the inane question of if they 38 00:02:21,280 --> 00:02:26,040 Speaker 1: can make something like a black box that can survive 39 00:02:26,080 --> 00:02:28,400 Speaker 1: an airplane car crash, why don't you just make the 40 00:02:28,440 --> 00:02:31,200 Speaker 1: whole airplane out of a black box material? And the 41 00:02:31,240 --> 00:02:34,919 Speaker 1: answer is because it wouldn't fly. Simple as that. Yeah, 42 00:02:35,120 --> 00:02:37,120 Speaker 1: so I'm glad we got that out of the way. Yeah, 43 00:02:37,160 --> 00:02:39,280 Speaker 1: and they're also we should go ahead and say right 44 00:02:39,320 --> 00:02:42,880 Speaker 1: up front, they're not black. Uh. They're generally like bright 45 00:02:42,919 --> 00:02:45,799 Speaker 1: orange with like reflective tape and things, because you want 46 00:02:45,800 --> 00:02:48,200 Speaker 1: to be able to find it. Yeah, amongst the rubble 47 00:02:48,680 --> 00:02:51,480 Speaker 1: as of the I think the sixties or seventies, there 48 00:02:51,520 --> 00:02:53,519 Speaker 1: became a mandate where you had to paint them bright 49 00:02:53,520 --> 00:02:55,720 Speaker 1: orange so you could find them. But they think that 50 00:02:55,760 --> 00:02:59,239 Speaker 1: they were called black boxes originally because either the original 51 00:02:59,280 --> 00:03:02,600 Speaker 1: ones were blacky or because it was kind of a 52 00:03:03,560 --> 00:03:06,960 Speaker 1: grim moniker because the boxes will become charred in the 53 00:03:06,960 --> 00:03:11,240 Speaker 1: wreckage and turn black. Yeah. I saw another explanation to that, 54 00:03:11,360 --> 00:03:13,320 Speaker 1: I don't think holds water. That they were initially like 55 00:03:13,440 --> 00:03:17,239 Speaker 1: round and red, and when they first debuted it, someone 56 00:03:17,280 --> 00:03:19,280 Speaker 1: in the room said, oh, what a nice black box, 57 00:03:19,880 --> 00:03:22,919 Speaker 1: as a smarmie thing to say, I guess about something 58 00:03:22,919 --> 00:03:24,880 Speaker 1: that's round and red. I don't know if that holds 59 00:03:24,880 --> 00:03:28,040 Speaker 1: water though. Yeah. It's weird all around. And apparently in 60 00:03:28,080 --> 00:03:30,840 Speaker 1: the aviation industry they don't call them black boxes anyway. 61 00:03:30,840 --> 00:03:33,239 Speaker 1: That's like something for the news media and jerks like us, 62 00:03:33,400 --> 00:03:38,560 Speaker 1: they probably call them crash survivalbal memory units. I think 63 00:03:38,560 --> 00:03:40,320 Speaker 1: what they call them is either one of the two 64 00:03:40,360 --> 00:03:45,280 Speaker 1: things that are either a flight data recorder or a 65 00:03:45,400 --> 00:03:51,240 Speaker 1: voice box. Well, there's a there's a lot of um. Yeah, 66 00:03:51,520 --> 00:03:54,640 Speaker 1: it's not that hard. But because of the media, and 67 00:03:54,680 --> 00:03:58,000 Speaker 1: in part because of this article, uh, it's very unclear 68 00:03:58,440 --> 00:04:02,800 Speaker 1: that black boxes are different things. Yeah, there's two different 69 00:04:03,480 --> 00:04:05,480 Speaker 1: We'll get into it, but there's really two different kinds. 70 00:04:05,480 --> 00:04:07,600 Speaker 1: And what you would think of as a black box 71 00:04:07,680 --> 00:04:12,520 Speaker 1: is actually a group of components the system that yeah, 72 00:04:12,560 --> 00:04:17,320 Speaker 1: that formed this system that's meant to record the flight 73 00:04:17,440 --> 00:04:22,440 Speaker 1: data and the cockpit um sounds, which is the discussion 74 00:04:22,520 --> 00:04:25,240 Speaker 1: and the beeps and the pings and all that of 75 00:04:25,360 --> 00:04:30,560 Speaker 1: every single flight that goes into the air, commercial flight yeah, um, 76 00:04:30,600 --> 00:04:33,200 Speaker 1: in order, and then it is housed in a way 77 00:04:33,240 --> 00:04:36,960 Speaker 1: that it will survive even a horrible plane crash. It's 78 00:04:36,960 --> 00:04:39,560 Speaker 1: frequently the only survivor of a plane crash. Yeah. And 79 00:04:39,560 --> 00:04:41,160 Speaker 1: we'll get to the testing of these, which I thought 80 00:04:41,240 --> 00:04:43,599 Speaker 1: was kind of the coolest part. Yeah, I thought so too. 81 00:04:43,800 --> 00:04:46,000 Speaker 1: And the whole point is, of course, is to get 82 00:04:46,040 --> 00:04:48,720 Speaker 1: all the data to figure out what happened in a 83 00:04:48,800 --> 00:04:53,640 Speaker 1: plane crash, what happened because very frequently that it's not. Again, 84 00:04:53,680 --> 00:04:57,120 Speaker 1: if it's the sole survivor, then there's no one there 85 00:04:57,160 --> 00:05:00,200 Speaker 1: to say, oh, well there's fire. There there's fire. It's 86 00:05:00,200 --> 00:05:02,400 Speaker 1: somebody lit a fire in the cabin and and the 87 00:05:02,400 --> 00:05:04,840 Speaker 1: whole the plain blue wall. Yeah, but you could hit 88 00:05:04,880 --> 00:05:07,800 Speaker 1: play and the pilot's going someone lit a fire in 89 00:05:07,839 --> 00:05:10,880 Speaker 1: the cabin, and there you have it. But it's a 90 00:05:10,920 --> 00:05:15,320 Speaker 1: little more complicated than that. Uh and goes back to uh. 91 00:05:15,360 --> 00:05:18,880 Speaker 1: In the nineteen forties there was a Finish aviation engineer 92 00:05:18,920 --> 00:05:26,480 Speaker 1: named V. A. Ho which doesn't sound finish umigration and 93 00:05:26,640 --> 00:05:30,640 Speaker 1: he did some of the first um flight recording was 94 00:05:30,680 --> 00:05:33,280 Speaker 1: something called the Mata Harre for World War two planes 95 00:05:33,440 --> 00:05:35,839 Speaker 1: test flights basically, but I think it was only like 96 00:05:35,920 --> 00:05:40,040 Speaker 1: instrument readings at the time. It wasn't recording uh uh 97 00:05:40,080 --> 00:05:43,600 Speaker 1: any voices like cockpit recording. Well, supposedly the Right Brothers 98 00:05:44,320 --> 00:05:47,679 Speaker 1: had some sort of recording device to record the propeller rotation. 99 00:05:47,720 --> 00:05:50,560 Speaker 1: That's pretty cool. Yeah, it's like there's been flight data 100 00:05:50,800 --> 00:05:53,400 Speaker 1: ever since there's been flight that's awesome. I found that 101 00:05:53,480 --> 00:05:56,200 Speaker 1: an Australian named David Warren was the one who really 102 00:05:56,240 --> 00:05:58,560 Speaker 1: came up with the black box recorder. Yeah, he's the 103 00:05:58,560 --> 00:06:03,000 Speaker 1: one that brought the voices into it, the actual audio recording. Okay, Yeah, 104 00:06:03,000 --> 00:06:06,440 Speaker 1: he was He was a member of a crash investigation 105 00:06:06,960 --> 00:06:09,360 Speaker 1: for a mysterious plane crash, and he thought it would 106 00:06:09,360 --> 00:06:11,360 Speaker 1: be really good if we had like a recording of 107 00:06:11,360 --> 00:06:13,919 Speaker 1: what was going on at the time. So he developed them. Yeah, 108 00:06:13,960 --> 00:06:16,200 Speaker 1: he's like that, you couldn't be too hard. And that 109 00:06:16,360 --> 00:06:20,000 Speaker 1: was the fifties, I believe, and they became widespread and 110 00:06:20,080 --> 00:06:23,440 Speaker 1: mandated in the sixties in Australia. It was the first 111 00:06:23,560 --> 00:06:27,760 Speaker 1: country and I guess even continent to make the mandatory. 112 00:06:28,080 --> 00:06:33,760 Speaker 1: So go uh Ozzy Yazzy Azzi so um. Initially the 113 00:06:34,320 --> 00:06:39,359 Speaker 1: black box recorders were UM recording on magnetic tape, and 114 00:06:39,400 --> 00:06:42,120 Speaker 1: then they moved in the strangely enough, in the late 115 00:06:42,200 --> 00:06:46,760 Speaker 1: nineties early two thousands. It wasn't until UM two eight 116 00:06:47,680 --> 00:06:51,200 Speaker 1: that they fully switched. Yeah that the f A mandated 117 00:06:51,520 --> 00:06:53,640 Speaker 1: in two thous five. There was a list of proposed 118 00:06:53,720 --> 00:06:56,160 Speaker 1: rules and one of them was, let's get rid of 119 00:06:56,200 --> 00:07:00,479 Speaker 1: magnetic recorders, which no one uses anymore. That's two thousand 120 00:07:00,480 --> 00:07:03,799 Speaker 1: five after all, and go to solid state digital record 121 00:07:04,160 --> 00:07:08,479 Speaker 1: yeah right, Uh, no cassettes even UM and uh they 122 00:07:09,160 --> 00:07:11,000 Speaker 1: the f A thought about it, and thought about and 123 00:07:11,040 --> 00:07:13,320 Speaker 1: thought about and finally said, okay, fine, we'll do that. 124 00:07:13,840 --> 00:07:16,640 Speaker 1: One of the big reasons why it was with magnetic 125 00:07:16,680 --> 00:07:19,480 Speaker 1: tapes you could just record the last half hour of 126 00:07:20,080 --> 00:07:23,520 Speaker 1: a cockpit conversation. Yeah, it would. It would rerecord over 127 00:07:23,560 --> 00:07:27,720 Speaker 1: itself every thirty minutes, which you know probably that's all 128 00:07:27,760 --> 00:07:29,920 Speaker 1: you need. Yeah, you want to hope that your plane 129 00:07:29,920 --> 00:07:33,720 Speaker 1: doesn't take thirty minutes to go down. Um. But the 130 00:07:33,960 --> 00:07:39,000 Speaker 1: the the big superiority that solid state has over that 131 00:07:39,120 --> 00:07:44,240 Speaker 1: is that the recording time is far greater, the recording 132 00:07:44,320 --> 00:07:49,640 Speaker 1: media is smaller, more durable if you were moving parts, yeah, 133 00:07:49,800 --> 00:07:52,600 Speaker 1: and so it can't break down as easily. And if 134 00:07:52,600 --> 00:07:56,480 Speaker 1: one part breaks, you can still take the solid state 135 00:07:56,560 --> 00:08:00,400 Speaker 1: memory sticks and reconfigure them and get the eat off 136 00:08:00,440 --> 00:08:03,280 Speaker 1: of them. Still. Yeah. They cost between ten and fifteen 137 00:08:03,280 --> 00:08:09,000 Speaker 1: grand each and are usually um comes straight from the manufacturer, 138 00:08:09,160 --> 00:08:13,080 Speaker 1: like they work with the airline manufact airplane manufacturers themselves 139 00:08:13,760 --> 00:08:16,320 Speaker 1: to like preinstall them on these planes. Right. Yeah, So 140 00:08:16,360 --> 00:08:19,000 Speaker 1: you have a black box manufacturer who sells them to 141 00:08:19,040 --> 00:08:22,800 Speaker 1: the airlines, who are the airplane manufacturers who sell the 142 00:08:22,840 --> 00:08:26,880 Speaker 1: airplanes to the airlines with the black boxes are installed. 143 00:08:26,880 --> 00:08:29,480 Speaker 1: It's like a part of the plane. That's right. Um, 144 00:08:29,520 --> 00:08:33,400 Speaker 1: so we should probably explain this now it's been long enough. 145 00:08:34,120 --> 00:08:37,560 Speaker 1: A black box can be one of two things, well, 146 00:08:37,600 --> 00:08:40,240 Speaker 1: one of three things really. Um. It can be the 147 00:08:40,360 --> 00:08:44,200 Speaker 1: flight data recorder, or it can be the cockpit voice recorder, 148 00:08:44,400 --> 00:08:47,640 Speaker 1: that's right, or it can be the crash survival baluh 149 00:08:48,000 --> 00:08:52,440 Speaker 1: memory unit. Black box refers to all three of those. Yeah, 150 00:08:52,720 --> 00:08:55,400 Speaker 1: the important thing, the only thing that really needs to 151 00:08:55,400 --> 00:08:59,040 Speaker 1: survive the crash is the crash survival of memory. That's 152 00:08:59,040 --> 00:09:03,040 Speaker 1: where the data is it and housed and um that's 153 00:09:03,080 --> 00:09:06,640 Speaker 1: the one that's super super beefed up to survive like 154 00:09:07,120 --> 00:09:10,640 Speaker 1: a nuclear war. Basically, so on any flight, on any 155 00:09:10,640 --> 00:09:14,360 Speaker 1: commercial flight, you have hundreds, if not thousands of sensors 156 00:09:15,000 --> 00:09:18,920 Speaker 1: going on at all times, and they are measuring things 157 00:09:19,040 --> 00:09:27,000 Speaker 1: like airspeed, altitude, UH, cabin pressure, cabin temperature, UM, wing 158 00:09:27,080 --> 00:09:31,959 Speaker 1: trim everything, What are your flaps doing? Yaw? Yeah, you 159 00:09:32,000 --> 00:09:35,000 Speaker 1: don't just guess it, yaw, you gotta measure it right, right, 160 00:09:35,080 --> 00:09:37,200 Speaker 1: And so all of this information is coming into the 161 00:09:37,240 --> 00:09:41,520 Speaker 1: flight computer and plugged into the flight computer is uh. Well, 162 00:09:41,640 --> 00:09:46,360 Speaker 1: basically it's like an upstream passive eavesdropping units called the 163 00:09:46,400 --> 00:09:50,319 Speaker 1: Flight Data Acquisition Unit, and it takes all of this UM. 164 00:09:50,320 --> 00:09:53,440 Speaker 1: That's up front, right, that's up front with the pilots UM, 165 00:09:53,480 --> 00:09:55,560 Speaker 1: and it takes all of this incoming information and it 166 00:09:55,600 --> 00:09:58,079 Speaker 1: records it. So not only is the are the pilots 167 00:09:58,559 --> 00:10:02,679 Speaker 1: and the the ground control getting all this information, but 168 00:10:02,720 --> 00:10:06,240 Speaker 1: it's being recorded as well, UM and it's being routed 169 00:10:06,280 --> 00:10:09,560 Speaker 1: to the recorders through the Flight Data Acquisition Unit. Right. 170 00:10:10,320 --> 00:10:13,079 Speaker 1: So also up front in the cockpit you're gonna have 171 00:10:13,480 --> 00:10:16,200 Speaker 1: at least four microphones and in some newer planes also 172 00:10:16,559 --> 00:10:19,960 Speaker 1: video cameras. Yeah, that's the newest, the latest, crazy, right, 173 00:10:20,320 --> 00:10:22,319 Speaker 1: which you can't do that on magnetic tape, you know 174 00:10:22,320 --> 00:10:24,320 Speaker 1: what I'm saying. Yeah, they have to start drinking vodka 175 00:10:25,440 --> 00:10:29,240 Speaker 1: instead of like brown liquors. What do you mean the pilots, 176 00:10:29,240 --> 00:10:31,679 Speaker 1: you know, like it's water. I'm just having some h 177 00:10:31,800 --> 00:10:37,880 Speaker 1: dwoh not not the Great Goose or Yeah, I'm joking. Okay, 178 00:10:38,040 --> 00:10:39,679 Speaker 1: all the pilots have been known to drink here and 179 00:10:39,679 --> 00:10:41,400 Speaker 1: there and they get in trouble. Yeah, they should get 180 00:10:41,400 --> 00:10:44,600 Speaker 1: in big trouble for you're the d D. Okay, if 181 00:10:44,600 --> 00:10:46,959 Speaker 1: you're an airline pilot, there's no way around it. The 182 00:10:47,040 --> 00:10:50,960 Speaker 1: only shouldn't do is drink and do drugs. So um, 183 00:10:51,040 --> 00:10:53,800 Speaker 1: up there to eaves drop on the pilots, and not 184 00:10:53,920 --> 00:10:56,320 Speaker 1: just the pilots, but also all the sounds going on 185 00:10:56,360 --> 00:11:00,520 Speaker 1: in the cockpit. Are these microphones and their recording everything 186 00:11:00,559 --> 00:11:03,600 Speaker 1: through the cockpit voice recorder? Yeah, and you talked about 187 00:11:03,640 --> 00:11:06,160 Speaker 1: the sounds, that's a big deal. Like not only do 188 00:11:06,200 --> 00:11:09,360 Speaker 1: you want to hear Captain Jim say, holy crap, our 189 00:11:09,400 --> 00:11:13,320 Speaker 1: wing is on fire, but they want to hear thirty 190 00:11:13,360 --> 00:11:16,160 Speaker 1: seconds before that if they hear just some weird noise. 191 00:11:16,720 --> 00:11:18,920 Speaker 1: And they're trained to pick up all that ambiance sound 192 00:11:18,920 --> 00:11:22,040 Speaker 1: and experts or trained too to listen out for things 193 00:11:22,040 --> 00:11:24,480 Speaker 1: that you would probably never notice. It's just a regular dude, 194 00:11:24,640 --> 00:11:26,360 Speaker 1: right exactly. And they can sit there and hear a 195 00:11:26,400 --> 00:11:28,640 Speaker 1: ping or a thud or a knock or a combination 196 00:11:28,679 --> 00:11:30,880 Speaker 1: of those things and be like, oh, I know what happened. 197 00:11:31,600 --> 00:11:35,240 Speaker 1: Somebody smoked in the laboratory and while they were on 198 00:11:35,280 --> 00:11:38,839 Speaker 1: their cell phone is loaded. Um, so you've got again, 199 00:11:38,880 --> 00:11:42,120 Speaker 1: you've got the cockpit voice recorder, you've got the flight 200 00:11:42,200 --> 00:11:45,640 Speaker 1: data recorder, and all of that info going out to 201 00:11:45,679 --> 00:11:48,640 Speaker 1: those two guys is going through the flight data Acquisition unit. 202 00:11:48,960 --> 00:11:51,080 Speaker 1: And it's sending the info all the way to the 203 00:11:51,080 --> 00:11:53,920 Speaker 1: back of the plane, where the cockpit voice recorder and 204 00:11:53,960 --> 00:11:56,520 Speaker 1: the flight data recorder are located. And why is it 205 00:11:56,559 --> 00:11:59,600 Speaker 1: located in the back, because the front of the plane 206 00:12:00,320 --> 00:12:03,000 Speaker 1: takes up most of the force of the impact, and 207 00:12:03,040 --> 00:12:06,200 Speaker 1: it's far likelier that something placed at the rear of 208 00:12:06,200 --> 00:12:09,560 Speaker 1: the plane, specifically like the tail cone or the aft 209 00:12:09,640 --> 00:12:13,560 Speaker 1: galley ceiling or something way in the back is going 210 00:12:13,640 --> 00:12:17,160 Speaker 1: to be likelier to survive because the rest gets mushed. Yeah, 211 00:12:17,200 --> 00:12:20,760 Speaker 1: we talked about that in our Surviving a Plane Crash episode. 212 00:12:21,120 --> 00:12:23,280 Speaker 1: And while they won't come out and say it out right, 213 00:12:23,679 --> 00:12:25,080 Speaker 1: it is a little bit safer in the back of 214 00:12:25,080 --> 00:12:29,240 Speaker 1: an airplane because you usually go nose down, and by 215 00:12:29,240 --> 00:12:31,720 Speaker 1: all accounts, if you drive a plane into a mountain, 216 00:12:33,200 --> 00:12:35,439 Speaker 1: captain and the co pilot are going to suffer the 217 00:12:35,440 --> 00:12:39,439 Speaker 1: worst of it. Maybe if you're in the back bathroom 218 00:12:39,480 --> 00:12:42,600 Speaker 1: having your cigarette, you're shaving like on airplane, you might 219 00:12:42,679 --> 00:12:47,079 Speaker 1: have a chance to survive, like cutting themselves. Uh and 220 00:12:47,400 --> 00:12:49,760 Speaker 1: speaking of mountains, chuck, this is good at places I 221 00:12:49,840 --> 00:12:52,240 Speaker 1: need to put it. There's some something called plane Crash 222 00:12:52,280 --> 00:12:57,040 Speaker 1: info dot com slash last words, and there's a lot 223 00:12:57,120 --> 00:12:59,000 Speaker 1: of It's not just this site. There's a lot of 224 00:12:59,000 --> 00:13:04,040 Speaker 1: sites that have UM recordings from black boxes from like 225 00:13:04,080 --> 00:13:07,600 Speaker 1: the last seconds or whatever. And this site also has 226 00:13:07,640 --> 00:13:09,880 Speaker 1: just like transcriptions of the last couple of sentences, and 227 00:13:09,920 --> 00:13:15,520 Speaker 1: one of them was mountains the last thing. But then 228 00:13:15,520 --> 00:13:18,160 Speaker 1: there's been there's other ones to like, um Ma, I 229 00:13:18,280 --> 00:13:21,200 Speaker 1: love you was one the last words of one pilot. 230 00:13:21,679 --> 00:13:25,560 Speaker 1: Another one was Pete sorry, so I get somebody screwed up. 231 00:13:25,640 --> 00:13:30,400 Speaker 1: Another one was hang on, what the hell is this? Yeah, 232 00:13:30,400 --> 00:13:32,679 Speaker 1: and then other ones seem like they don't realize what's 233 00:13:32,720 --> 00:13:34,760 Speaker 1: about to happen. This isn't as bad as I thought 234 00:13:34,800 --> 00:13:38,520 Speaker 1: it would be, right, Yeah, yeah, but it's pretty interesting stuff. 235 00:13:38,600 --> 00:13:42,000 Speaker 1: Some of it's pretty grim. Some of it's super sad. Yeah, 236 00:13:42,720 --> 00:13:44,680 Speaker 1: it's like not an uplifting thing. Start on read on 237 00:13:44,720 --> 00:13:47,320 Speaker 1: a Friday afternoon. Oh no, it's not uplifting, but it's 238 00:13:47,440 --> 00:13:50,400 Speaker 1: it's definitely interesting. Yeah. I would not recommend reading that 239 00:13:50,559 --> 00:13:53,560 Speaker 1: before you take a flight. No. As a matter of fact, 240 00:13:53,640 --> 00:13:57,000 Speaker 1: Umi was traveling UM recently while I was researching this, 241 00:13:57,080 --> 00:13:58,840 Speaker 1: and I made you send it to I was like, 242 00:13:59,000 --> 00:14:01,240 Speaker 1: I can't send her this. He's gotta fly back here. 243 00:14:01,600 --> 00:14:05,959 Speaker 1: That's awful. UM. Alright, so we talked, Uh, let's go 244 00:14:06,000 --> 00:14:08,560 Speaker 1: ahead and talk about the flight the flight data recorder. UM. 245 00:14:08,600 --> 00:14:13,080 Speaker 1: You mentioned that they are all kinds of um of 246 00:14:13,360 --> 00:14:16,160 Speaker 1: data being recorded, like up to seven hundred types of 247 00:14:16,240 --> 00:14:19,880 Speaker 1: data can be recorded. UM. Like they can tell when 248 00:14:19,880 --> 00:14:22,520 Speaker 1: you just turn a switch on, that's like it's logged. 249 00:14:22,520 --> 00:14:25,760 Speaker 1: All of a sudden, captain turned on, even interior cabin 250 00:14:25,880 --> 00:14:29,000 Speaker 1: light switch, you know, that's all recorded. And UM. The 251 00:14:29,120 --> 00:14:34,400 Speaker 1: f a A they require pre two thousand two planes 252 00:14:34,440 --> 00:14:37,320 Speaker 1: to have a minimum of eleven and twenty parameters. If 253 00:14:37,320 --> 00:14:40,200 Speaker 1: it was built after two thousand to um at least 254 00:14:40,240 --> 00:14:43,440 Speaker 1: eight parameters, right, I don't see why they just don't 255 00:14:43,880 --> 00:14:47,600 Speaker 1: log at all if they can. Well, apparently like that 256 00:14:47,600 --> 00:14:51,200 Speaker 1: that rule that forced up to eight parameters be recorded 257 00:14:51,240 --> 00:14:54,480 Speaker 1: like cost the airline industry like three million bucks or something. 258 00:14:54,520 --> 00:14:57,240 Speaker 1: And that's the reason they're notoriously tight. So that's why 259 00:14:57,360 --> 00:15:00,320 Speaker 1: they keep fighting it. And it's the NTSB that's say like, 260 00:15:00,600 --> 00:15:03,160 Speaker 1: let's push this along. It's two thousand five, we need 261 00:15:03,160 --> 00:15:06,560 Speaker 1: to stop using magnetic reel reel and the f a 262 00:15:06,560 --> 00:15:08,600 Speaker 1: A is like, I don't know, Well, the f A 263 00:15:08,760 --> 00:15:12,920 Speaker 1: is being pushed around by the airline industry well scary enough. Um, 264 00:15:13,040 --> 00:15:14,560 Speaker 1: I guess it's a good time to mention this. There 265 00:15:14,640 --> 00:15:17,400 Speaker 1: was something called the Safe Act Safe A v S 266 00:15:17,440 --> 00:15:21,800 Speaker 1: Asian and Flight Enhancement Act, and it's been up twice 267 00:15:22,480 --> 00:15:25,880 Speaker 1: and has not passed this legislation either time. And all 268 00:15:25,920 --> 00:15:30,000 Speaker 1: they're trying to do is provide a second recorder and 269 00:15:30,320 --> 00:15:33,120 Speaker 1: one of them should be deployable in the rear, which 270 00:15:33,160 --> 00:15:36,200 Speaker 1: makes sense, like if the plane hits an impact, this 271 00:15:36,320 --> 00:15:39,440 Speaker 1: thing pops off the back of the plane altogether and 272 00:15:40,200 --> 00:15:46,720 Speaker 1: a little clost like. I guess so because because they said, uh, 273 00:15:46,960 --> 00:15:50,600 Speaker 1: the f a A has a long history of delaying uh, 274 00:15:50,800 --> 00:15:53,800 Speaker 1: much needed upgrades in this equipment, and I guess it's 275 00:15:53,800 --> 00:15:57,160 Speaker 1: because the price or the airplane lobby. Yeah. When you 276 00:15:57,240 --> 00:16:01,520 Speaker 1: when your federal agency is actually like a safeguard to 277 00:16:01,560 --> 00:16:05,320 Speaker 1: protect the finances of the industry, is regulating, that's not good. No, 278 00:16:05,440 --> 00:16:10,480 Speaker 1: it's not. I can't everybody just do things right. I know, 279 00:16:10,800 --> 00:16:13,960 Speaker 1: it's frustrating, and money is typically at the root of 280 00:16:14,000 --> 00:16:17,200 Speaker 1: it all, you know, it always is. Yeah, all right, 281 00:16:17,240 --> 00:16:20,040 Speaker 1: So we talked a little bit about the testing. I 282 00:16:20,080 --> 00:16:21,520 Speaker 1: guess we should just talk about what these things are 283 00:16:21,520 --> 00:16:25,520 Speaker 1: built out of, why they survive that the CSMU back 284 00:16:25,600 --> 00:16:30,800 Speaker 1: in Roswell in New Mexico. No, but there are three 285 00:16:30,920 --> 00:16:34,480 Speaker 1: layers of materials to keep these things safe. Um, you 286 00:16:34,560 --> 00:16:37,360 Speaker 1: got your aluminum housing on the outside of it, and 287 00:16:37,400 --> 00:16:41,360 Speaker 1: it holds all your memory cards. No, the aluminum is inside. 288 00:16:42,640 --> 00:16:44,760 Speaker 1: Oh yeah, yeah, yeah, yeah, Okay, that makes sense. It's 289 00:16:44,760 --> 00:16:46,440 Speaker 1: the weakest link, you know what I mean, it's on 290 00:16:46,480 --> 00:16:50,440 Speaker 1: the inside surrounding it's the last stand of protection. I guess, right, 291 00:16:50,440 --> 00:16:52,600 Speaker 1: that is like you said, it's holding the memory cards, 292 00:16:52,840 --> 00:16:55,960 Speaker 1: which are the one thing you really want to survive, 293 00:16:56,120 --> 00:17:01,120 Speaker 1: the only thing. And this is right right, Yeah, I 294 00:17:01,200 --> 00:17:03,440 Speaker 1: guess it's a good point. And this is the crash 295 00:17:03,520 --> 00:17:06,679 Speaker 1: survivable memory Unit, which is actually a part of the 296 00:17:06,720 --> 00:17:11,400 Speaker 1: flight data recorder and the cockpit voice recorder. But it's 297 00:17:11,440 --> 00:17:17,440 Speaker 1: also the separate It's kind of like the Holy see no, 298 00:17:17,920 --> 00:17:21,240 Speaker 1: the Holy of Holies, the temple within the Temple of Jerusalem. Yeah, 299 00:17:21,240 --> 00:17:23,320 Speaker 1: like everything else will get mangled and it doesn't matter. 300 00:17:23,600 --> 00:17:26,120 Speaker 1: But all you needed, like you said, are those memory cards. Right, Okay, 301 00:17:26,119 --> 00:17:28,639 Speaker 1: So so go ahead. There's an aluminum housing around the 302 00:17:28,640 --> 00:17:30,919 Speaker 1: memory card, right, and then around that you have it 303 00:17:31,000 --> 00:17:34,879 Speaker 1: insulated with a dry silica one inch of it and 304 00:17:35,440 --> 00:17:37,640 Speaker 1: that is because a lot of times some planes crash 305 00:17:37,720 --> 00:17:40,040 Speaker 1: they catch on fire. Yeah, you want to retard fire. 306 00:17:40,400 --> 00:17:43,960 Speaker 1: Put a niche of silicus stuff around this, around whatever 307 00:17:44,000 --> 00:17:46,600 Speaker 1: you want, your hand, your head, sure, just do it. 308 00:17:47,000 --> 00:17:49,399 Speaker 1: You won't get h And then around that is your 309 00:17:49,400 --> 00:17:52,360 Speaker 1: outer shell. And it's either stainless steel or titanium. It's 310 00:17:52,359 --> 00:17:55,600 Speaker 1: about a quarter inch thick. And that's like you know 311 00:17:55,640 --> 00:17:59,520 Speaker 1: that you're bomb casing and all of that is why 312 00:17:59,640 --> 00:18:01,520 Speaker 1: you can't bill a plane out of all this. It 313 00:18:01,520 --> 00:18:05,000 Speaker 1: would be too heavy. And so this this one to 314 00:18:05,240 --> 00:18:10,000 Speaker 1: three punch of a crash revivable memory unit. Um, it's 315 00:18:10,000 --> 00:18:13,600 Speaker 1: a cylinder. Did you say that? I thought it was implicit. 316 00:18:13,880 --> 00:18:17,320 Speaker 1: It's just so imagine like a steel box. And you 317 00:18:17,359 --> 00:18:19,720 Speaker 1: can also go onto how stuff works and type in um, 318 00:18:19,760 --> 00:18:24,040 Speaker 1: how black boxes working. It'll bring up images. But imagine 319 00:18:24,040 --> 00:18:26,359 Speaker 1: like a steel box that forms like an L on 320 00:18:26,440 --> 00:18:30,120 Speaker 1: its back right, so the foot is sticking upward into 321 00:18:30,119 --> 00:18:33,480 Speaker 1: the air. And then on the part that's along the 322 00:18:33,520 --> 00:18:36,760 Speaker 1: ground now of the L is it's cylinder that's coming up. 323 00:18:37,200 --> 00:18:40,000 Speaker 1: Looks like it's it's holding some oil or something like. 324 00:18:40,040 --> 00:18:42,919 Speaker 1: That's an oil cylinder. It's like a fat squat barrel. 325 00:18:44,040 --> 00:18:49,120 Speaker 1: Then Attached to that is this little tube another cylinder 326 00:18:49,160 --> 00:18:52,760 Speaker 1: but longer and shorter, that serves as the handle for 327 00:18:52,800 --> 00:18:56,600 Speaker 1: the whole unit. But it's also a beacon. Yeah, and 328 00:18:56,680 --> 00:18:59,600 Speaker 1: that's super important. Um And actually we'll get into that. 329 00:19:00,080 --> 00:19:03,440 Speaker 1: But you've got to find these things, you know. It 330 00:19:03,480 --> 00:19:05,560 Speaker 1: does no good if it's hidden behind a tree or 331 00:19:05,640 --> 00:19:08,520 Speaker 1: at the bottom of the ocean. They like to hide, 332 00:19:08,600 --> 00:19:11,240 Speaker 1: they do. So we talked about some of the testing 333 00:19:11,440 --> 00:19:15,160 Speaker 1: that these things go through, and it's pretty awesome. Um. 334 00:19:15,200 --> 00:19:20,359 Speaker 1: They do one, two, three, four, five, six tests, the 335 00:19:20,359 --> 00:19:23,200 Speaker 1: first of which is just a basic crash impact. They 336 00:19:23,240 --> 00:19:26,120 Speaker 1: shoot it out of an air cannon at thirty four 337 00:19:26,240 --> 00:19:31,480 Speaker 1: hundred g s into an aluminum honeycomb and it smashes 338 00:19:31,520 --> 00:19:34,879 Speaker 1: it with a force equal to times its own weight. 339 00:19:35,240 --> 00:19:37,159 Speaker 1: It's just like, I want to see this thing in 340 00:19:37,200 --> 00:19:40,600 Speaker 1: super SlowMo basically, which not only does this simulate the 341 00:19:40,680 --> 00:19:46,160 Speaker 1: impact of a major plane crash, it actually probably overstates 342 00:19:46,240 --> 00:19:49,840 Speaker 1: the force. I think they overstate everything, you know, and 343 00:19:49,960 --> 00:19:52,200 Speaker 1: these things survived to say, okay, good, all right, let's 344 00:19:52,200 --> 00:19:54,000 Speaker 1: take it on to the next test, and the flight 345 00:19:54,200 --> 00:19:57,560 Speaker 1: data recorders like wait what yeah, exactly, and they take 346 00:19:57,600 --> 00:19:59,600 Speaker 1: it onto the pin drop, which I think it's funny 347 00:19:59,640 --> 00:20:02,200 Speaker 1: that they the pin drop has nothing to do with it. Sound, 348 00:20:02,320 --> 00:20:06,200 Speaker 1: it's like engineering humor. Yeah. They take like a five 349 00:20:06,600 --> 00:20:10,720 Speaker 1: pound weight with a quarter inch steel pin coming out 350 00:20:10,720 --> 00:20:12,280 Speaker 1: of the end of it. It's like a little spike, 351 00:20:12,480 --> 00:20:16,040 Speaker 1: and they drop it from ten ft the spike onto 352 00:20:16,480 --> 00:20:21,160 Speaker 1: the weakest axis of the uh, the black box. It's 353 00:20:21,160 --> 00:20:24,959 Speaker 1: like a puncture test. Yeah, and it nothing happens, so 354 00:20:25,000 --> 00:20:26,679 Speaker 1: they move it on to the next test. Yeah. The 355 00:20:26,720 --> 00:20:30,280 Speaker 1: static crush, which would be a good band name. Uh. 356 00:20:30,480 --> 00:20:33,800 Speaker 1: Five minutes of five thousand pounds per square much pressure 357 00:20:34,280 --> 00:20:37,320 Speaker 1: applied to the six major access points. So it's just 358 00:20:37,359 --> 00:20:40,119 Speaker 1: a constant, not an impact thing. But just let me 359 00:20:40,160 --> 00:20:42,159 Speaker 1: see if I can just crush you over time with 360 00:20:42,240 --> 00:20:45,679 Speaker 1: brute force. Yeah. It's like a headlock. Yeah, the worst 361 00:20:45,680 --> 00:20:48,919 Speaker 1: headlock you can ever imagine. And then the fire test, 362 00:20:49,040 --> 00:20:53,560 Speaker 1: which uh they fire a propane fireball with three burners 363 00:20:53,760 --> 00:20:57,159 Speaker 1: at about two thousand degrees fahrenheit for an hour and 364 00:20:57,240 --> 00:20:58,800 Speaker 1: just let it sit there and see if it melts 365 00:20:58,880 --> 00:21:02,359 Speaker 1: or does anything or explodes or whatever. Yea, it just 366 00:21:02,400 --> 00:21:06,480 Speaker 1: sits there. Um, and then the planes frequently go down. 367 00:21:06,880 --> 00:21:09,720 Speaker 1: Well when they go down, they frequently go down into 368 00:21:09,760 --> 00:21:12,520 Speaker 1: the ocean or the sea. So your black box has 369 00:21:12,560 --> 00:21:16,120 Speaker 1: to survive underwater. So they do a deep sea immersion 370 00:21:16,160 --> 00:21:19,640 Speaker 1: test UM, which is like a pressurized tank of water 371 00:21:19,720 --> 00:21:22,480 Speaker 1: for twenty four hours. Uh. And then they also do 372 00:21:22,520 --> 00:21:25,959 Speaker 1: a saltwater submersion test, so this thing has to basically 373 00:21:25,960 --> 00:21:29,239 Speaker 1: sit around in saltwater for thirty days, that's right. And 374 00:21:29,560 --> 00:21:33,199 Speaker 1: finally they will let it soak in other types of 375 00:21:33,240 --> 00:21:37,680 Speaker 1: fluids like jet fuel and lubricants and fire extinguisher chemicals 376 00:21:37,680 --> 00:21:40,000 Speaker 1: and anything else in a plane that it might end 377 00:21:40,080 --> 00:21:43,480 Speaker 1: up submerged in. And if they can withstand sitting in 378 00:21:43,560 --> 00:21:45,760 Speaker 1: jet fuel for a period of time, then you're good 379 00:21:45,800 --> 00:21:48,200 Speaker 1: to go. Yeah. And then after all this they put 380 00:21:48,280 --> 00:21:53,920 Speaker 1: a little um mortarboard on the the cylinder and send 381 00:21:53,920 --> 00:21:56,840 Speaker 1: it along its way to be installed in an airplane. 382 00:21:57,200 --> 00:22:00,760 Speaker 1: That's right where it's Sadly, we'll only be used if 383 00:22:00,800 --> 00:22:04,959 Speaker 1: something really bad happens. Alright, So we've set this all up. 384 00:22:05,160 --> 00:22:09,120 Speaker 1: These things are sturdy, they're solid, they're good to go. Uh. 385 00:22:09,560 --> 00:22:11,440 Speaker 1: I think we should talk about what happens in the 386 00:22:11,480 --> 00:22:17,600 Speaker 1: event of a crash right after this place. All right, 387 00:22:17,680 --> 00:22:21,359 Speaker 1: So your plane is crashed, Yeah, we're both dead, but 388 00:22:21,480 --> 00:22:24,159 Speaker 1: the black box has survived. It lives on what happens 389 00:22:24,200 --> 00:22:27,720 Speaker 1: to it. Well, they have to find it first. Um And, 390 00:22:27,960 --> 00:22:30,400 Speaker 1: like we said, these things are tested to make sure 391 00:22:30,440 --> 00:22:34,320 Speaker 1: that they can withstand deep sea and salt water immersion, 392 00:22:34,680 --> 00:22:38,720 Speaker 1: which they sometimes have to. UM And in the event 393 00:22:38,800 --> 00:22:41,080 Speaker 1: that they are going to go into the water. The 394 00:22:41,160 --> 00:22:44,800 Speaker 1: little handle that has an underwater beacon installed in it 395 00:22:45,560 --> 00:22:48,800 Speaker 1: actually has this water detector and when water comes in 396 00:22:48,880 --> 00:22:51,120 Speaker 1: contact with the beacon, it starts to set it off 397 00:22:51,760 --> 00:22:54,119 Speaker 1: and it sends out a pink I think every minute 398 00:22:54,160 --> 00:22:58,720 Speaker 1: or thirty seconds for the next thirty days or something like. Yeah, 399 00:22:58,800 --> 00:23:01,720 Speaker 1: it's one per second for a month. Yeah. Um. And 400 00:23:01,840 --> 00:23:04,600 Speaker 1: this ping you couldn't hear it if you were listening 401 00:23:04,640 --> 00:23:07,680 Speaker 1: for it, but if you were listening through sonar, you 402 00:23:07,720 --> 00:23:10,760 Speaker 1: would be able to pick it up. And the beacon 403 00:23:10,840 --> 00:23:13,000 Speaker 1: sends out the ping and the people go find the 404 00:23:13,000 --> 00:23:16,480 Speaker 1: ping and they get it. They can transmit ideally, but 405 00:23:16,560 --> 00:23:19,480 Speaker 1: it can transmit up to fourteen thou feet, which is 406 00:23:19,480 --> 00:23:24,440 Speaker 1: pretty impressive, right, um And and if you can find 407 00:23:24,480 --> 00:23:28,280 Speaker 1: the beacon thanks to the ping, that's awesome. There have 408 00:23:28,440 --> 00:23:32,920 Speaker 1: been cases where the black boxes have been found long 409 00:23:32,960 --> 00:23:36,399 Speaker 1: after the ping stopped. Um Air France flight four or 410 00:23:36,440 --> 00:23:39,040 Speaker 1: four seven when I think two thousand nine and went 411 00:23:39,080 --> 00:23:42,200 Speaker 1: down in the Atlantic, remember that one. It was awful, 412 00:23:42,280 --> 00:23:45,320 Speaker 1: like it just disappeared into the Atlantic and they couldn't 413 00:23:45,359 --> 00:23:48,320 Speaker 1: find the wreckage for a very long time. I tried 414 00:23:48,359 --> 00:23:50,119 Speaker 1: to block out plane crashes. It was. It was a 415 00:23:50,119 --> 00:23:53,760 Speaker 1: bad one. It was one of the worst, most recent ones. Um. 416 00:23:53,800 --> 00:23:57,760 Speaker 1: But they couldn't find the black box for two years, 417 00:23:58,520 --> 00:24:01,359 Speaker 1: and they finally found it in sea water at twelve 418 00:24:01,359 --> 00:24:04,320 Speaker 1: thou feet after two years. And when they brought the 419 00:24:04,600 --> 00:24:06,879 Speaker 1: both of the black boxes up, they were able to 420 00:24:06,880 --> 00:24:09,080 Speaker 1: get all of the data off of them. They were 421 00:24:09,160 --> 00:24:11,480 Speaker 1: well made. Did it was it dumb luck or were 422 00:24:11,520 --> 00:24:13,959 Speaker 1: they searching for it? Oh? They're searching for it, Okay, 423 00:24:14,080 --> 00:24:17,520 Speaker 1: even though it stopp pinging, they just kept looking. Uh. 424 00:24:17,520 --> 00:24:22,040 Speaker 1: So you do recover it, hopefully, and then you need 425 00:24:22,080 --> 00:24:24,480 Speaker 1: to analyze the data. So they're going to transport it 426 00:24:24,520 --> 00:24:27,439 Speaker 1: to the h to a lab at the NTSP the 427 00:24:27,560 --> 00:24:32,960 Speaker 1: National Transportation Safety Board. We should say, the the country 428 00:24:33,000 --> 00:24:36,480 Speaker 1: that this happens in, or if it's like an international 429 00:24:36,520 --> 00:24:39,320 Speaker 1: waters the country that the airline is registered in is 430 00:24:39,359 --> 00:24:43,240 Speaker 1: responsible for leading the investigation. So in the United States 431 00:24:43,280 --> 00:24:48,199 Speaker 1: would be the NTSB. Okay, yeah, sure. Um. And just 432 00:24:48,240 --> 00:24:51,960 Speaker 1: like any relic you find, if you know about finding 433 00:24:52,040 --> 00:24:55,040 Speaker 1: undersea items that have been in salt water, you want 434 00:24:55,080 --> 00:24:58,840 Speaker 1: to transport that in its own state that you found it, 435 00:24:58,920 --> 00:25:01,600 Speaker 1: so in its own yeah, like if it's it's the 436 00:25:01,640 --> 00:25:04,040 Speaker 1: same thing as if you find a piece of sunken treasure. 437 00:25:04,400 --> 00:25:06,119 Speaker 1: You don't want to bring it out and dry it 438 00:25:06,160 --> 00:25:08,119 Speaker 1: off with a hair dryer. You want to keep it 439 00:25:08,160 --> 00:25:10,560 Speaker 1: submerged in saltwater because that's where it's been living. And 440 00:25:10,600 --> 00:25:14,280 Speaker 1: that's the sucking treasure pro tip from Chuck. I did 441 00:25:14,320 --> 00:25:17,960 Speaker 1: an article on that. Actually that's how I know this. Um. 442 00:25:18,000 --> 00:25:20,439 Speaker 1: But yeah, so if if they find it in the ocean, 443 00:25:20,520 --> 00:25:22,600 Speaker 1: they want to transport it in salt water and a 444 00:25:22,640 --> 00:25:26,439 Speaker 1: cooler to a lab where they can really treat it right, 445 00:25:26,560 --> 00:25:29,240 Speaker 1: give it the V I P treatment. Yeah. Um. And 446 00:25:29,359 --> 00:25:32,639 Speaker 1: if the whole black box is still intact, yeah, you 447 00:25:32,640 --> 00:25:36,320 Speaker 1: can actually just use it's it's computer interface. It's already 448 00:25:36,359 --> 00:25:39,080 Speaker 1: installed this part of the recorder. Yeah, you can just 449 00:25:39,080 --> 00:25:41,360 Speaker 1: plug it in and download all the stuff off of it. Yeah, 450 00:25:41,400 --> 00:25:44,119 Speaker 1: it can be super quick. But oftentimes that stuff, like 451 00:25:44,160 --> 00:25:46,840 Speaker 1: we said, is mangled and burned away, and so you 452 00:25:46,840 --> 00:25:50,080 Speaker 1: have to just take the memory sticks and then you know, 453 00:25:50,280 --> 00:25:52,199 Speaker 1: hook it up to a different machine so you can 454 00:25:52,240 --> 00:25:55,359 Speaker 1: retrieve the data, that's right, which takes a little longer. Yeah, 455 00:25:55,359 --> 00:25:59,360 Speaker 1: it can take weeks or months. When you get the data. Obviously, 456 00:25:59,359 --> 00:26:03,800 Speaker 1: when you have the flight data recorder data, you can 457 00:26:03,840 --> 00:26:07,720 Speaker 1: feed that into a computer and create a simulation using 458 00:26:07,800 --> 00:26:11,879 Speaker 1: a model to visualize what the plane was doing based 459 00:26:11,880 --> 00:26:14,240 Speaker 1: on all those readings from all those different arrays. When 460 00:26:14,240 --> 00:26:16,600 Speaker 1: you put them all together, it can create a computer 461 00:26:16,680 --> 00:26:19,000 Speaker 1: model of the plane to show what it was doing 462 00:26:19,040 --> 00:26:22,320 Speaker 1: at the time of the crash. Um, the cockpit voice 463 00:26:22,320 --> 00:26:26,320 Speaker 1: recorder uses a little more of human ingenuity to piece 464 00:26:26,359 --> 00:26:30,199 Speaker 1: it together, and this takes way longer. Yeah. One thing 465 00:26:30,200 --> 00:26:34,520 Speaker 1: you're gonna have is um a representative from the airline. 466 00:26:34,960 --> 00:26:38,560 Speaker 1: You're gonna have a representative from the plane builder because 467 00:26:38,560 --> 00:26:41,720 Speaker 1: they don't like their planes to go down. Um, there's 468 00:26:41,760 --> 00:26:44,280 Speaker 1: gonna be uh, I guess whatever country or in your 469 00:26:44,359 --> 00:26:46,679 Speaker 1: version of the NTSB is going to be there. And 470 00:26:46,720 --> 00:26:49,760 Speaker 1: then sometimes they might have a translator or language specialist, 471 00:26:50,600 --> 00:26:54,159 Speaker 1: depending on you know what nationality your your pilot was, 472 00:26:54,760 --> 00:26:57,240 Speaker 1: because i'mout to translate some stuff and you have people 473 00:26:57,240 --> 00:27:00,480 Speaker 1: who are trained in deciphering beeps and pings and Knox 474 00:27:00,720 --> 00:27:04,320 Speaker 1: and airline cockpits, and they put all this together. It's 475 00:27:04,320 --> 00:27:07,760 Speaker 1: a pretty interesting job, you know. Um. And you you 476 00:27:08,040 --> 00:27:10,639 Speaker 1: take that information, you put it together with the model, 477 00:27:10,880 --> 00:27:15,679 Speaker 1: the simulation from the plane, the flight data recorder, and 478 00:27:15,720 --> 00:27:18,760 Speaker 1: then these days also the flight computers send out warning 479 00:27:18,800 --> 00:27:22,000 Speaker 1: messages like flight four four seven air France. It's sent 480 00:27:22,040 --> 00:27:25,400 Speaker 1: out like twenty four warning messages um in the four 481 00:27:25,440 --> 00:27:28,399 Speaker 1: minutes before it crashed. So they had that already on hand, 482 00:27:28,920 --> 00:27:31,560 Speaker 1: but nothing else. Yes, And then they started to piece 483 00:27:31,560 --> 00:27:34,320 Speaker 1: it together after they went and got the wreckage, which 484 00:27:34,359 --> 00:27:38,040 Speaker 1: we should say in some cases, when possible, they'll actually 485 00:27:38,280 --> 00:27:41,919 Speaker 1: piece the entire plane back together to Oh yeah, I 486 00:27:41,920 --> 00:27:43,840 Speaker 1: didn't know that. Yeah, they'll get like a huge airplane 487 00:27:43,840 --> 00:27:46,160 Speaker 1: hangar and take all the wreckage and pieces together piece 488 00:27:46,200 --> 00:27:48,560 Speaker 1: by piece and try to get the plane back together 489 00:27:48,600 --> 00:27:51,680 Speaker 1: to help that to help to help give a complete 490 00:27:51,680 --> 00:27:54,040 Speaker 1: picture of what the heck happened. Did you see that 491 00:27:54,119 --> 00:27:57,199 Speaker 1: the flight the Denzel Washington movie? No, I heard it 492 00:27:57,240 --> 00:28:00,879 Speaker 1: was so depressing. It was good. Wasn't they filmed that 493 00:28:00,960 --> 00:28:05,000 Speaker 1: here too in Atlanta? But yeah, it was intense for sure. Okay, 494 00:28:05,080 --> 00:28:07,159 Speaker 1: I'll check it out and then chuck Um, it's not 495 00:28:07,240 --> 00:28:11,040 Speaker 1: just airplanes where you can find black boxes, buddy, that's right. 496 00:28:11,480 --> 00:28:16,160 Speaker 1: They're on trains planes already on planes, they're on trains, 497 00:28:16,720 --> 00:28:20,560 Speaker 1: and sort of a newish thing is putting versions of 498 00:28:20,560 --> 00:28:24,000 Speaker 1: these and cars, um, either to give you like an 499 00:28:24,000 --> 00:28:26,720 Speaker 1: insurance break. I think you can opt for these sometimes 500 00:28:27,720 --> 00:28:30,600 Speaker 1: to prove that you're a safe driver and get it 501 00:28:30,640 --> 00:28:33,239 Speaker 1: basically tracks like how fast you go and if you're 502 00:28:33,280 --> 00:28:37,159 Speaker 1: speeding and taking turns too fast and stuff like that. Yeah, 503 00:28:37,200 --> 00:28:40,120 Speaker 1: but they're a little controversial, I guess because I think 504 00:28:40,160 --> 00:28:45,480 Speaker 1: in England you can actually get traffic tickets based on right. Yeah, 505 00:28:45,680 --> 00:28:49,280 Speaker 1: I knew that was coming. Yeah, but some there's some 506 00:28:49,320 --> 00:28:53,520 Speaker 1: car manufacturers that manufacture basically flight data recorders into their 507 00:28:53,520 --> 00:28:59,240 Speaker 1: cars already. It's not necessarily recording like your cockpit conversation 508 00:28:59,320 --> 00:29:01,680 Speaker 1: or anything like that, but it is keeping track of 509 00:29:01,720 --> 00:29:06,320 Speaker 1: your car. It's like, um, you you know how like 510 00:29:06,600 --> 00:29:08,440 Speaker 1: your car will tell you that your tire pressure is 511 00:29:08,480 --> 00:29:11,200 Speaker 1: low or your doors open or something like that. There's 512 00:29:11,200 --> 00:29:13,560 Speaker 1: something that's recording all that stuff, including all of your 513 00:29:13,600 --> 00:29:17,680 Speaker 1: engine stuff and everything else that's part of your car too, 514 00:29:17,680 --> 00:29:21,160 Speaker 1: which amounts to a black box. Because we left out 515 00:29:21,400 --> 00:29:23,240 Speaker 1: we said that. You know, the point of having a 516 00:29:23,280 --> 00:29:25,480 Speaker 1: black box is to figure out what the heck happened. 517 00:29:25,840 --> 00:29:28,240 Speaker 1: We didn't quite go far enough, because the point of 518 00:29:28,240 --> 00:29:30,280 Speaker 1: figuring out what the heck happened, it's such as to 519 00:29:30,360 --> 00:29:33,840 Speaker 1: satisfied curiosity. But if there's a problem that's going to 520 00:29:34,400 --> 00:29:38,160 Speaker 1: translate to other planes too, mechanical failure, right, you want 521 00:29:38,160 --> 00:29:40,040 Speaker 1: to go be able to fix it. Or if there's 522 00:29:40,040 --> 00:29:43,760 Speaker 1: a way to make planes safer in the future, um 523 00:29:43,880 --> 00:29:46,360 Speaker 1: or prevent an accident. That's the whole point of the 524 00:29:46,400 --> 00:29:50,760 Speaker 1: black boxes, to learn from tragedy. Yeah, they should put 525 00:29:50,760 --> 00:29:56,560 Speaker 1: the voice recorders in cars, for right, Yeah, for d 526 00:29:56,640 --> 00:30:02,600 Speaker 1: why crash? This guy sounds drunk? Pull them over all right, Focus, focus, 527 00:30:02,640 --> 00:30:04,520 Speaker 1: Like you start hearing stuff like that, you're in big trouble. 528 00:30:05,000 --> 00:30:06,840 Speaker 1: Like no one else was in the car saying that 529 00:30:06,880 --> 00:30:09,280 Speaker 1: out loud to yourself, but you're arguing about whether you 530 00:30:09,280 --> 00:30:15,640 Speaker 1: should focus. I shouldn't be driving, it's fine, right, we 531 00:30:15,680 --> 00:30:19,120 Speaker 1: shouldn't be joking about that. That's like super sad. Well, 532 00:30:19,160 --> 00:30:21,560 Speaker 1: this is a pretty pretty sad episode. Yeah, but we 533 00:30:21,560 --> 00:30:24,200 Speaker 1: should make pretty sad episode suggested by like a four 534 00:30:24,280 --> 00:30:28,680 Speaker 1: year old I know what's going on with Cormack I 535 00:30:28,760 --> 00:30:30,640 Speaker 1: don't know. We'll have to get to the bottom of that. 536 00:30:32,560 --> 00:30:34,080 Speaker 1: I don't know what kind of parenting is going on. 537 00:30:34,520 --> 00:30:38,720 Speaker 1: And as hood, you are great parenting. I'm sure I 538 00:30:38,760 --> 00:30:41,920 Speaker 1: don't have anything else. I don't either. You got anything else? 539 00:30:41,960 --> 00:30:45,360 Speaker 1: I got nothing else. Well, we should like Cormack who 540 00:30:46,080 --> 00:30:50,400 Speaker 1: this is how we originally got the idea for this episode. Um, 541 00:30:50,440 --> 00:30:53,240 Speaker 1: we should let him play us out to listener mail. 542 00:30:53,760 --> 00:30:56,479 Speaker 1: Let's hear it.

We've had a 566 00:32:07,800 --> 00:32:11,040 Speaker 1: great response with our episode on salt, so thanks for 567 00:32:11,080 --> 00:32:13,640 Speaker 1: everyone that wrote in so far. A slight correction for 568 00:32:13,680 --> 00:32:16,000 Speaker 1: you guys on Kosher salt. You work correct on its 569 00:32:16,040 --> 00:32:18,160 Speaker 1: use of drawing blood out of meat, as eating blood 570 00:32:18,200 --> 00:32:20,600 Speaker 1: is against Jewish dietary laws. Simply salting the meat, though, 571 00:32:20,600 --> 00:32:23,800 Speaker 1: will not make it kosher, which is a common misconception. 572 00:32:24,040 --> 00:32:25,840 Speaker 1: To have a kosher meat, Firstly, you must have a 573 00:32:25,880 --> 00:32:29,680 Speaker 1: kosher animal, one that choose its cud and has split hoofs. 574 00:32:30,360 --> 00:32:32,720 Speaker 1: While pigs have split hooves, they do not chew their cut. 575 00:32:33,080 --> 00:32:36,080 Speaker 1: They're not kosher. Cannot be a scavenger, so no catfish 576 00:32:36,120 --> 00:32:39,640 Speaker 1: or lobsters. No lobster, I saw that felt. Oh yeah, 577 00:32:39,640 --> 00:32:42,240 Speaker 1: that's right. Although fish is not considered meat, it is 578 00:32:42,240 --> 00:32:45,120 Speaker 1: called parv p A r V, essentially meaning neutral, as 579 00:32:45,160 --> 00:32:47,960 Speaker 1: in not meat or dairy, which are never eaten together. 580 00:32:48,760 --> 00:32:50,680 Speaker 1: And it cannot be a predator. So no hawks or 581 00:32:50,760 --> 00:32:55,560 Speaker 1: chickens or no chicken hawks are chickens predators. Um, if 582 00:32:55,600 --> 00:32:57,360 Speaker 1: you're a worm of chickens of predator, you know what 583 00:32:57,440 --> 00:32:59,760 Speaker 1: I mean? All right? Secondly, guys, and this is key. 584 00:32:59,760 --> 00:33:02,520 Speaker 1: The weill must be killed in a ritual called shifting 585 00:33:02,760 --> 00:33:08,440 Speaker 1: by trained ritual s s H E, K H T 586 00:33:08,600 --> 00:33:12,640 Speaker 1: I n G the second H through me. This process 587 00:33:12,680 --> 00:33:15,800 Speaker 1: involves a super perfectly sharp, rectangular ended knife. It's about 588 00:33:15,800 --> 00:33:19,680 Speaker 1: twice as long as the particular animal's neck. It is 589 00:33:19,720 --> 00:33:22,720 Speaker 1: forbidden to stab or tear the flesh, hence the squared 590 00:33:22,760 --> 00:33:26,920 Speaker 1: inn and sharpness and one swift motion. The esophagus, trachea, 591 00:33:27,040 --> 00:33:30,360 Speaker 1: herotid arteries, and jugular veins are all cut. The animal 592 00:33:30,400 --> 00:33:35,760 Speaker 1: may not even feel it. Well, just's to say uh, 593 00:33:35,800 --> 00:33:38,560 Speaker 1: and we'll pass out and then die in seconds. The 594 00:33:38,560 --> 00:33:41,240 Speaker 1: blood is then drained from the animal, and after butchering, 595 00:33:41,320 --> 00:33:43,800 Speaker 1: it assaulted with coash or salt to draw out the 596 00:33:43,840 --> 00:33:46,440 Speaker 1: remaining blood and rinsed. You know, I knew a lot 597 00:33:46,480 --> 00:33:49,640 Speaker 1: of that because I read this very very interesting article 598 00:33:49,800 --> 00:33:53,680 Speaker 1: in Harper's Um several months ago, and this guy basically 599 00:33:53,720 --> 00:33:58,000 Speaker 1: infiltrated the meat industry and like Nebraska or something like that, 600 00:33:58,440 --> 00:34:02,840 Speaker 1: and he describes like kosher process of slaughter and how 601 00:34:02,880 --> 00:34:05,760 Speaker 1: different it is from regular process, but that they have 602 00:34:05,800 --> 00:34:08,759 Speaker 1: this special guy who's like a rabbi or something who 603 00:34:08,760 --> 00:34:11,560 Speaker 1: works on this line at the slaughterhouse in in Nebraska. 604 00:34:11,640 --> 00:34:15,040 Speaker 1: He's like a super specialized dude throat cutter. Yeah wow. 605 00:34:15,200 --> 00:34:19,040 Speaker 1: But he uses like this incredibly sharp instrument. It's really good. 606 00:34:19,200 --> 00:34:22,000 Speaker 1: He's a schector. It's a really really interesting article. I 607 00:34:22,040 --> 00:34:24,560 Speaker 1: can't remember the name of it, but I recommend anybody 608 00:34:24,560 --> 00:34:26,319 Speaker 1: going and finding it. You know what, maybe you can 609 00:34:26,360 --> 00:34:29,759 Speaker 1: post that in your blog. Do I have a blog? Yeah? 610 00:34:30,000 --> 00:34:32,399 Speaker 1: You do. Your blog posts about the best things you've 611 00:34:32,400 --> 00:34:34,239 Speaker 1: read this week. Oh yeah, yeah, maybe you should throw 612 00:34:34,239 --> 00:34:37,160 Speaker 1: it in there. All right. So those are the very 613 00:34:37,160 --> 00:34:40,680 Speaker 1: basics of kosher meat. Guys. Jewish dietary laws and certification 614 00:34:40,760 --> 00:34:43,560 Speaker 1: are much too lengthy for an email or a single 615 00:34:43,600 --> 00:34:47,160 Speaker 1: episode for that matter. It's very convoluted, highly recommend a 616 00:34:47,160 --> 00:34:49,840 Speaker 1: delightfully with the book called Kosher for the Clueless but 617 00:34:49,920 --> 00:34:55,480 Speaker 1: Curious by Simon Episdorff. I hope this is making words 618 00:34:55,480 --> 00:34:58,040 Speaker 1: and names. I hope I've shed some light on this 619 00:34:58,120 --> 00:35:02,080 Speaker 1: highly complex aspect of Judaism. That's for Michelle and Cedar Park, Texas. 620 00:35:02,200 --> 00:35:06,360 Speaker 1: Thanks Michelle, just near Austin, UH.
