1 00:00:00,200 --> 00:00:06,400 Speaker 1: Brought to you by the all New Toyota Corolla. Welcome 2 00:00:06,440 --> 00:00:09,680 Speaker 1: to Stuff you Should Know from House Stuff, Work Stops 3 00:00:09,720 --> 00:00:18,800 Speaker 1: dot Com. Hey, and welcome to the podcast. I'm Josh Clark. 4 00:00:19,079 --> 00:00:22,639 Speaker 1: That's Charles W. Chuck. Chucker's Bryant. This is stuff you 5 00:00:22,640 --> 00:00:24,840 Speaker 1: should know. You can just call us MAV and Goose 6 00:00:24,880 --> 00:00:31,280 Speaker 1: for this one. No you can't. Okay, okay, it depends 7 00:00:31,320 --> 00:00:34,600 Speaker 1: who's MAV and who's Goose. Well, the the re email, 8 00:00:34,600 --> 00:00:36,639 Speaker 1: I said that it's very appropriate for the show. Why 9 00:00:37,360 --> 00:00:42,239 Speaker 1: because Goose died because his ejection seed malfunction. I know 10 00:00:42,680 --> 00:00:44,640 Speaker 1: he hit his head on the canopy. I know I 11 00:00:44,640 --> 00:00:48,320 Speaker 1: broke his neck. Is because he'd angered God earlier that day, 12 00:00:48,479 --> 00:00:52,680 Speaker 1: I guess so, so I'll be Goose. Are you planning 13 00:00:52,760 --> 00:00:55,880 Speaker 1: on dying? I'm just planning on you feeling guilt for 14 00:00:55,920 --> 00:00:58,840 Speaker 1: the rest of your life. You caused the spin by 15 00:00:58,880 --> 00:01:03,040 Speaker 1: being a guns blazing maverick. That is true, but I 16 00:01:03,080 --> 00:01:06,520 Speaker 1: would be like, I didn't design the injection seat. That's 17 00:01:06,560 --> 00:01:08,440 Speaker 1: the guy who should feel guilty for the rest of 18 00:01:08,480 --> 00:01:12,200 Speaker 1: his life. I'm gonna go get a taco. Um. Yeah, 19 00:01:12,200 --> 00:01:15,480 Speaker 1: I'm gonna go ride my motorcycle around Miramar. It's funny. 20 00:01:15,480 --> 00:01:17,240 Speaker 1: When I saw top Gun, and I may have talked 21 00:01:17,280 --> 00:01:19,520 Speaker 1: about this before, I remember thinking at the time, like, people, 22 00:01:20,160 --> 00:01:22,920 Speaker 1: you don't die in training exercises like that, that's so hollywood. 23 00:01:22,959 --> 00:01:25,479 Speaker 1: It up as a matter of fact, that happened very 24 00:01:25,520 --> 00:01:28,080 Speaker 1: well two years ago. It happens all the time. You 25 00:01:28,120 --> 00:01:30,040 Speaker 1: never hear about it. Yeah, there's the guys that make 26 00:01:30,080 --> 00:01:35,200 Speaker 1: the papers, my paper. It doesn't. It's sad that it doesn't, 27 00:01:35,240 --> 00:01:40,960 Speaker 1: but uh, yeah, like it. It happens. Our military died 28 00:01:41,080 --> 00:01:44,880 Speaker 1: during training and it's it's awful. My brother in law 29 00:01:44,959 --> 00:01:47,559 Speaker 1: is a helicopter pilos, you know, and he's lost several 30 00:01:47,560 --> 00:01:50,800 Speaker 1: friends through the years in training. Yeah. Is it in 31 00:01:50,880 --> 00:01:55,000 Speaker 1: crashes or from ejection seats crashes? Yeah? Um, there was 32 00:01:55,040 --> 00:01:57,560 Speaker 1: a guy in two thousand and eleven. You know the 33 00:01:57,560 --> 00:02:02,080 Speaker 1: Blue Angels, the what there's also the Red Arrows. Yeah, 34 00:02:02,080 --> 00:02:04,320 Speaker 1: I know the Blue Angels. Okay, Well the Red Arrows 35 00:02:04,480 --> 00:02:09,640 Speaker 1: um are another formation flying team, like just basically some 36 00:02:09,760 --> 00:02:13,320 Speaker 1: really great pilots, and one of them was killed when 37 00:02:13,400 --> 00:02:17,360 Speaker 1: his ejection seat went off while his plane was motionless. 38 00:02:17,400 --> 00:02:20,120 Speaker 1: The ejection seat just accidentally went off. That's a zero 39 00:02:20,240 --> 00:02:23,079 Speaker 1: zero ejection and that what that's called. Yes, but that 40 00:02:23,160 --> 00:02:26,400 Speaker 1: means you're on the ground and you're not flying at all. Right, Um, 41 00:02:26,560 --> 00:02:29,000 Speaker 1: but I think the problem is the plane didn't realize 42 00:02:29,000 --> 00:02:33,120 Speaker 1: where the ejection. Um, the sequencer didn't realize that it 43 00:02:33,200 --> 00:02:37,040 Speaker 1: was a zero zero ejection because the paras you never deployed. 44 00:02:37,440 --> 00:02:39,840 Speaker 1: So he died when he fell back down to earth 45 00:02:41,000 --> 00:02:43,359 Speaker 1: from a couple hundred feet out. I guess, yeah, well, 46 00:02:44,120 --> 00:02:46,200 Speaker 1: well this all makes sense in a second. Um. You 47 00:02:46,200 --> 00:02:48,120 Speaker 1: know what I think as a primer before, if you're 48 00:02:48,160 --> 00:02:51,760 Speaker 1: at home listening, you can go to the YouTube site 49 00:02:52,440 --> 00:02:57,320 Speaker 1: and look up, look up like ejection seat and there's 50 00:02:57,320 --> 00:03:00,720 Speaker 1: one like slow motion on the ground zero zero ejection 51 00:03:00,880 --> 00:03:03,519 Speaker 1: from film from different angles that really shows how it 52 00:03:03,560 --> 00:03:06,520 Speaker 1: all works. It's pretty cool and um, you really get 53 00:03:06,520 --> 00:03:08,519 Speaker 1: a sense of like what they do, go up a 54 00:03:08,560 --> 00:03:12,480 Speaker 1: couple hundred feet Yeah, and quick too, very quick. Um. 55 00:03:12,639 --> 00:03:14,680 Speaker 1: This so this is this is not even my intro. 56 00:03:15,840 --> 00:03:22,080 Speaker 1: I've got an intro, Chuck. There's a guy in World 57 00:03:22,120 --> 00:03:24,679 Speaker 1: War Two who is a tail gunner on a B 58 00:03:24,880 --> 00:03:29,400 Speaker 1: seventeen flying Fortress. And this man's name was Alan McGhee, 59 00:03:29,440 --> 00:03:33,320 Speaker 1: who's staff sergeant. And if you were a tail gunner 60 00:03:33,480 --> 00:03:36,920 Speaker 1: on the B seventeen, you were basically cramped into this 61 00:03:36,960 --> 00:03:41,040 Speaker 1: little gun turret with your knees up to your chest, 62 00:03:41,160 --> 00:03:44,240 Speaker 1: your heads poking out in a little clear canopy shell. Yes, 63 00:03:44,800 --> 00:03:48,560 Speaker 1: and you had no room whatsoever to wear a parachute. 64 00:03:49,200 --> 00:03:52,360 Speaker 1: You had to keep it in the cockpit with everybody else. Well. 65 00:03:52,520 --> 00:03:55,720 Speaker 1: Alan McGee is on this B seventeen called the Snap 66 00:03:55,800 --> 00:04:01,320 Speaker 1: Crackle Pop, and they're flying on a mission over France. 67 00:04:01,520 --> 00:04:04,840 Speaker 1: Satan is there, which was also known as Flack City 68 00:04:04,920 --> 00:04:08,880 Speaker 1: because of the anti aircraft guns down on the ground. 69 00:04:10,280 --> 00:04:13,520 Speaker 1: And sure enough, the Snap Crackle Pop took some flak lost. 70 00:04:13,520 --> 00:04:16,159 Speaker 1: A wing had a couple of holes in it, and 71 00:04:16,920 --> 00:04:21,839 Speaker 1: these holes in turn put holes into McGee's parachute. So 72 00:04:22,400 --> 00:04:25,960 Speaker 1: he needs to bail out. He finds a hole that's 73 00:04:25,960 --> 00:04:29,000 Speaker 1: been blown into the side of the the Snap Crackle 74 00:04:29,040 --> 00:04:33,120 Speaker 1: Pop and jumps out at twenty thousand feet with a 75 00:04:33,160 --> 00:04:36,279 Speaker 1: parachute with holes in it, with no parachute whatsoever, because 76 00:04:36,279 --> 00:04:38,719 Speaker 1: he was like why bother. He just knew he needed 77 00:04:38,760 --> 00:04:41,200 Speaker 1: to get out of the plane quick and he later 78 00:04:41,200 --> 00:04:45,279 Speaker 1: said that he thought he had a parachute. Yes, He 79 00:04:45,480 --> 00:04:50,560 Speaker 1: fall twenty two thousand feet more than four miles to 80 00:04:50,640 --> 00:04:54,480 Speaker 1: the ground, goes right through the skylight in the satan 81 00:04:54,560 --> 00:05:00,600 Speaker 1: Asaire Trades train station and Lands and Lives. He had 82 00:05:00,839 --> 00:05:03,280 Speaker 1: a um how does that happen? He had I'll tell 83 00:05:03,320 --> 00:05:05,640 Speaker 1: you a second. He had a broken right leg, broken 84 00:05:05,760 --> 00:05:10,040 Speaker 1: right ankle, nearly severed right arm, twenty eight shrapnel wounds 85 00:05:10,160 --> 00:05:12,520 Speaker 1: from the shards of glass because he fell right through 86 00:05:12,560 --> 00:05:16,960 Speaker 1: plate glass from again twenty two thousand ft four miles 87 00:05:16,960 --> 00:05:20,160 Speaker 1: above the ground, and he lived to tell about it. 88 00:05:20,400 --> 00:05:22,920 Speaker 1: A German doctor apparently took very good care of him, 89 00:05:23,160 --> 00:05:26,200 Speaker 1: and he later on said, you know, publicly thanked the guy, 90 00:05:26,360 --> 00:05:30,360 Speaker 1: even though he was a Nazi doctor, um for saving 91 00:05:30,360 --> 00:05:33,320 Speaker 1: his life. And so I'm reading about this and this 92 00:05:33,440 --> 00:05:36,000 Speaker 1: is just astounding. I'm looking into it more and more 93 00:05:36,000 --> 00:05:41,160 Speaker 1: and more, and there's no trick. It's just physics. Um. 94 00:05:41,360 --> 00:05:45,480 Speaker 1: This physicist Dr Seth Eisenberg, he's not a physicist, he's 95 00:05:45,520 --> 00:05:50,240 Speaker 1: a trauma specialist. He said on Popular Mechanics that there's 96 00:05:50,240 --> 00:05:53,640 Speaker 1: really no magic here. That he was going. McGee was 97 00:05:53,720 --> 00:05:56,479 Speaker 1: going as fast as he would have been had he 98 00:05:56,560 --> 00:06:00,160 Speaker 1: jumped off of something like a twelve story building. Once 99 00:06:00,200 --> 00:06:03,120 Speaker 1: you reach terminal velocity, it's all the same, whether it's 100 00:06:03,120 --> 00:06:08,840 Speaker 1: four miles or whether it's twenty feet. Um, it's still 101 00:06:08,839 --> 00:06:12,320 Speaker 1: pretty spectacular that he fell four miles through the roof 102 00:06:12,400 --> 00:06:17,279 Speaker 1: of a building and survived. The point of all this 103 00:06:17,360 --> 00:06:18,919 Speaker 1: is so the point was though, that he could have 104 00:06:18,920 --> 00:06:20,960 Speaker 1: fallen off a twelve story building through the plate glasses 105 00:06:20,960 --> 00:06:23,919 Speaker 1: and everyone had been like, Wow, that's pretty awesome, but 106 00:06:24,000 --> 00:06:26,679 Speaker 1: not miraculous. Yeah, compared to four miles it's not. Okay, 107 00:06:26,760 --> 00:06:29,919 Speaker 1: I got you. It's still be pretty miraculous that he survived. 108 00:06:30,200 --> 00:06:33,960 Speaker 1: Used to die, you know, twelve story building. He's pretty 109 00:06:34,000 --> 00:06:37,839 Speaker 1: banged up. Yeah, So the point is him just jumping 110 00:06:37,880 --> 00:06:39,880 Speaker 1: out of the the hole in the side of the 111 00:06:39,920 --> 00:06:43,599 Speaker 1: snap crackle pop was not that different from how you 112 00:06:43,600 --> 00:06:45,840 Speaker 1: would get out of a plane in World War Two. 113 00:06:46,200 --> 00:06:49,560 Speaker 1: You just kind of opened up the canopy and jumped 114 00:06:49,560 --> 00:06:52,479 Speaker 1: out and then you know, opened your parachute at the 115 00:06:52,480 --> 00:06:58,440 Speaker 1: appropriate height right or altitude. When that's fine with planes, 116 00:06:58,520 --> 00:07:02,240 Speaker 1: propeller planes, but once jets were introduced, you can't do 117 00:07:02,279 --> 00:07:05,520 Speaker 1: that because they're going so much faster than a propeller 118 00:07:05,560 --> 00:07:08,559 Speaker 1: plane does. You can't just jump out speed of sound, dude. 119 00:07:09,040 --> 00:07:13,640 Speaker 1: So around the time the jet age began, a company 120 00:07:13,880 --> 00:07:17,640 Speaker 1: named Martin Baxter, a British aviation company, started really looking 121 00:07:17,680 --> 00:07:21,520 Speaker 1: into the idea of the ejection seat, and we have 122 00:07:21,640 --> 00:07:27,240 Speaker 1: that today thanks in large part to them. Hats off, Yeah, 123 00:07:27,680 --> 00:07:31,320 Speaker 1: real men of genius. Uh So. An ejection seat, if 124 00:07:31,320 --> 00:07:34,040 Speaker 1: you don't know, just to put it very simply, is 125 00:07:34,560 --> 00:07:38,040 Speaker 1: a seat that is ejected from the aircraft ob jet, 126 00:07:38,160 --> 00:07:42,240 Speaker 1: can be a helicopter. Um. And it's a very much 127 00:07:42,280 --> 00:07:45,960 Speaker 1: a last second maybe not last second, but it's the 128 00:07:46,040 --> 00:07:50,560 Speaker 1: last ditch effort to save yourself when you know that 129 00:07:50,560 --> 00:07:54,160 Speaker 1: that aircraft is going down, right, Yeah, it's the that's 130 00:07:54,200 --> 00:07:58,480 Speaker 1: your last resort. You don't do that frivolously because number one, 131 00:07:59,160 --> 00:08:02,360 Speaker 1: airplanes are expense Yeah, they're also very dangerous when they 132 00:08:02,400 --> 00:08:06,680 Speaker 1: crash land. Yeah, and you really I think it's probably 133 00:08:06,760 --> 00:08:09,560 Speaker 1: bad form to scuttle your plane when you still have 134 00:08:09,640 --> 00:08:12,120 Speaker 1: control of it. Yeah, I think so. Like, hey, I 135 00:08:12,160 --> 00:08:16,280 Speaker 1: wonder what this thing does. Um. And the article points 136 00:08:16,280 --> 00:08:18,600 Speaker 1: out and it's once you really read this thing, it's 137 00:08:18,640 --> 00:08:21,200 Speaker 1: really true. It's one of the most complex parts of 138 00:08:21,240 --> 00:08:24,080 Speaker 1: an aircraft. Could be thousands of parts in some of these, 139 00:08:24,800 --> 00:08:28,760 Speaker 1: and the object is to get the pilot out and 140 00:08:28,800 --> 00:08:32,120 Speaker 1: then disattached from that seat without hitting any part of 141 00:08:32,120 --> 00:08:35,400 Speaker 1: the aircraft. So like up and out in a way 142 00:08:35,480 --> 00:08:38,560 Speaker 1: out of harm's way, at which point, um you become 143 00:08:38,640 --> 00:08:42,400 Speaker 1: a parachuter. Yeah, that's that's exactly right. You want to 144 00:08:42,440 --> 00:08:44,920 Speaker 1: get the pilot into the position to just parachute down 145 00:08:44,920 --> 00:08:48,480 Speaker 1: into the ground, and it all happens and under four seconds, 146 00:08:48,559 --> 00:08:52,160 Speaker 1: and about two to three of those seconds is the 147 00:08:52,200 --> 00:08:55,720 Speaker 1: actual parachute aspect, Like the ejection part is all in 148 00:08:55,720 --> 00:08:57,679 Speaker 1: about a second and a second and a half. It's 149 00:08:57,720 --> 00:09:00,920 Speaker 1: pretty pretty amazing, and we're gonna tell you how it works. 150 00:09:01,000 --> 00:09:05,960 Speaker 1: So the process of it is fairly simple. The procedure, right, 151 00:09:06,000 --> 00:09:09,920 Speaker 1: it's like, just get the pilot out of the plane 152 00:09:10,400 --> 00:09:13,440 Speaker 1: above it, out of the way of the plane crash, yeah, 153 00:09:13,480 --> 00:09:17,920 Speaker 1: and let the parachute happen to its thing. Right. But 154 00:09:18,000 --> 00:09:20,800 Speaker 1: when you look at the mechanisms involved in this, it's 155 00:09:20,840 --> 00:09:26,319 Speaker 1: extremely detailed, especially since when you had the first microprocessor 156 00:09:26,720 --> 00:09:29,640 Speaker 1: in charge of ejection seats. It's really neat. Yes, So 157 00:09:29,720 --> 00:09:32,160 Speaker 1: let's talk about ejection seats. Let's talk about the basics. 158 00:09:32,200 --> 00:09:35,640 Speaker 1: You've got. First of all, the seat, Yes, the seat 159 00:09:35,679 --> 00:09:38,640 Speaker 1: is connected. It's in the cockpit obviously, and it's attached 160 00:09:38,679 --> 00:09:43,559 Speaker 1: to rails um by by way of some rollers. So 161 00:09:43,760 --> 00:09:46,040 Speaker 1: you might think like the seats just like bolted to 162 00:09:46,080 --> 00:09:48,440 Speaker 1: the floor. It's not. It's on rollers on these rails 163 00:09:48,679 --> 00:09:51,360 Speaker 1: because those rails and rollers are going to do the 164 00:09:51,400 --> 00:09:55,720 Speaker 1: initial guidance of the chair at the proper angle out 165 00:09:55,720 --> 00:09:59,360 Speaker 1: of the aircraft. Right. You can't just go up, you 166 00:09:59,400 --> 00:10:02,319 Speaker 1: can't just go forward, you can't just go back right. 167 00:10:03,640 --> 00:10:07,240 Speaker 1: And when you go up those rails, you actually have 168 00:10:07,360 --> 00:10:09,640 Speaker 1: to go at a certain amount of speed, and that 169 00:10:09,800 --> 00:10:13,480 Speaker 1: speed has to be slightly more than the aircraft is 170 00:10:13,520 --> 00:10:17,480 Speaker 1: going or else you're not going to clear the cockpit. Yeah, 171 00:10:17,600 --> 00:10:20,240 Speaker 1: So to do that, you have what's called the catapult, 172 00:10:20,440 --> 00:10:22,960 Speaker 1: which is usually a charge. Yeah, that's what gets you 173 00:10:23,000 --> 00:10:27,160 Speaker 1: going up the rails and initially out. Um. Then there 174 00:10:27,200 --> 00:10:30,960 Speaker 1: will be a secondary rocket that that shoots you up 175 00:10:30,960 --> 00:10:33,200 Speaker 1: another couple of hundred feet and clear the tail of 176 00:10:33,200 --> 00:10:36,920 Speaker 1: the plane and everything. Um. And it does it quick too, 177 00:10:37,240 --> 00:10:38,920 Speaker 1: It does it really quick. And this is all This 178 00:10:38,960 --> 00:10:41,320 Speaker 1: whole system is called an A E S and Assisted 179 00:10:41,400 --> 00:10:45,679 Speaker 1: Egress system egress meaning exit or a way out. Um, 180 00:10:45,840 --> 00:10:48,000 Speaker 1: little on the nose, but I get it. Yeah, that's 181 00:10:48,000 --> 00:10:52,840 Speaker 1: the military. Um. And Uh, the canopy is you know, 182 00:10:52,880 --> 00:10:55,040 Speaker 1: if you've ever seen like a fighter jet, they've got 183 00:10:55,040 --> 00:10:58,520 Speaker 1: the clear clear canopy above them where they like wave 184 00:10:58,600 --> 00:11:00,959 Speaker 1: and like give the thumbs upside in the black Power 185 00:11:01,040 --> 00:11:02,880 Speaker 1: sign and all that stuff. Yeah, where they shoot a 186 00:11:02,880 --> 00:11:05,480 Speaker 1: bird at the Russian is in top Gun. Remember they 187 00:11:05,480 --> 00:11:07,880 Speaker 1: flew right on the upside down right above them. That 188 00:11:07,960 --> 00:11:13,800 Speaker 1: seemed almost incredible. It's very incredible. Yeah, and probably not real. Well, 189 00:11:13,840 --> 00:11:18,240 Speaker 1: that's what I mean, Tony Scott r I p um. 190 00:11:18,280 --> 00:11:20,200 Speaker 1: So you got the canopy, and the problem with the 191 00:11:20,240 --> 00:11:23,880 Speaker 1: canopy is it shouldn't be there when you're trying to eject. 192 00:11:25,760 --> 00:11:28,240 Speaker 1: It's right, So part of the assisted egre system is 193 00:11:28,240 --> 00:11:31,760 Speaker 1: the canopy actually uh blowing and getting the heck out 194 00:11:31,800 --> 00:11:33,360 Speaker 1: of the way. If you don't have a canopy, you 195 00:11:33,440 --> 00:11:38,000 Speaker 1: might have an escape hatch built into the roof. And um. 196 00:11:38,160 --> 00:11:41,200 Speaker 1: You do all this by pulling a lever either between 197 00:11:41,200 --> 00:11:42,960 Speaker 1: your legs or by your side or in the case 198 00:11:43,000 --> 00:11:45,320 Speaker 1: of Top Gun. I looked at the clip today. It's 199 00:11:45,320 --> 00:11:49,320 Speaker 1: too two loops behind their head that they pulled. Or 200 00:11:49,480 --> 00:11:51,240 Speaker 1: sometimes you might pull a face curtain down in front 201 00:11:51,240 --> 00:11:53,880 Speaker 1: of your face, which serves two purposes. It gets the 202 00:11:53,880 --> 00:11:57,040 Speaker 1: whole system moving and protects your face. And it's not 203 00:11:57,160 --> 00:12:02,679 Speaker 1: like a veil, no, it's like it's sturdy. Yeah. Well, 204 00:12:03,080 --> 00:12:04,280 Speaker 1: and I think of, like, you know what I think 205 00:12:04,280 --> 00:12:06,160 Speaker 1: of when I think of curtain and planes, I think 206 00:12:06,200 --> 00:12:09,120 Speaker 1: of like what they used to separate first class from 207 00:12:09,440 --> 00:12:12,040 Speaker 1: from coach. We don't want this to bereta. So here's 208 00:12:12,080 --> 00:12:15,160 Speaker 1: this black Lacey. He's like, I don't. I don't want 209 00:12:15,160 --> 00:12:18,040 Speaker 1: to see having to bail out. So those are some 210 00:12:18,080 --> 00:12:20,120 Speaker 1: of the ways. You know, there's all different kinds of systems, 211 00:12:20,120 --> 00:12:22,400 Speaker 1: but that's generally how it works. Okay, so we got 212 00:12:22,400 --> 00:12:25,360 Speaker 1: the general part before we go. Any let's do a 213 00:12:25,400 --> 00:12:27,240 Speaker 1: message break and let's do that. Yeah. They's about to 214 00:12:27,240 --> 00:12:40,120 Speaker 1: get really good though. Mm hm. Okay, So them's the basics. 215 00:12:40,200 --> 00:12:43,040 Speaker 1: We're talking about the basics. Yeah, let's get into the 216 00:12:43,440 --> 00:12:46,680 Speaker 1: nuts and bolts of this as it were. Yeah, and 217 00:12:46,720 --> 00:12:51,200 Speaker 1: bolts will come into play actually specifics. Um. So let's 218 00:12:51,200 --> 00:12:52,920 Speaker 1: talk about the seat. You've got your bucket, which is 219 00:12:52,920 --> 00:12:55,960 Speaker 1: where you sit. Um it. Also the seat comes with 220 00:12:55,960 --> 00:12:58,240 Speaker 1: survival equipment, which is kind of nice. Yeah, I licked 221 00:12:58,280 --> 00:13:02,160 Speaker 1: it up. Some survival packs have like oxygen, so if 222 00:13:02,280 --> 00:13:04,960 Speaker 1: you are bailing out and you're you're not attest to 223 00:13:04,960 --> 00:13:08,360 Speaker 1: oxygen at a high altitude, you're gonna need it. Um. 224 00:13:08,480 --> 00:13:12,679 Speaker 1: They have rifles in them. Which is just cool um blankets. 225 00:13:13,000 --> 00:13:16,560 Speaker 1: What I don't get is the seat ejects from the person. 226 00:13:16,640 --> 00:13:19,880 Speaker 1: So is the safety pack this stays attest Okay, so 227 00:13:19,920 --> 00:13:22,000 Speaker 1: you're still in a sitting position with this thing attached 228 00:13:22,040 --> 00:13:24,960 Speaker 1: to you or it's a test your back Okay, Yeah, 229 00:13:25,000 --> 00:13:27,719 Speaker 1: I was confused by that too. I'm glad you took 230 00:13:27,760 --> 00:13:31,560 Speaker 1: the time. Um, we cover the canopy. The catapult is 231 00:13:31,600 --> 00:13:35,080 Speaker 1: obviously what initiates it, and it's operated with, like you said, 232 00:13:35,160 --> 00:13:38,360 Speaker 1: ballistic cartridge. There's a lot of explosions going. You're riding 233 00:13:38,360 --> 00:13:41,240 Speaker 1: a bullet right then, yeah, pretty much, then you're going 234 00:13:41,400 --> 00:13:44,160 Speaker 1: to catapult the rails. You got your drug parachute, which 235 00:13:44,200 --> 00:13:47,880 Speaker 1: is a small parachute five two to five ft in 236 00:13:47,880 --> 00:13:52,440 Speaker 1: diameter that it initially pops out to uh, sort of 237 00:13:52,760 --> 00:13:54,880 Speaker 1: balance you and make sure you're not just flying all 238 00:13:54,880 --> 00:13:56,480 Speaker 1: over the place and slow you down a little bit, 239 00:13:56,640 --> 00:13:58,520 Speaker 1: right because I mean, if you're going in at even 240 00:13:58,559 --> 00:14:02,160 Speaker 1: a slight angle at the speed of sound, possibly, yes, 241 00:14:02,360 --> 00:14:05,160 Speaker 1: you need to slow down kind of quick. And the 242 00:14:05,200 --> 00:14:09,199 Speaker 1: drug parachute is just that little one like uh, then 243 00:14:09,320 --> 00:14:13,040 Speaker 1: the drags that's exactly what it is. And sometimes you 244 00:14:13,040 --> 00:14:14,640 Speaker 1: know how they'll have like a small one, and then 245 00:14:14,679 --> 00:14:17,280 Speaker 1: a big one. They have that too on injection seats 246 00:14:17,320 --> 00:14:20,560 Speaker 1: as well. And then the drug parachute also very commonly, 247 00:14:20,680 --> 00:14:24,520 Speaker 1: um will trip the larger parachute too after a certain 248 00:14:24,560 --> 00:14:29,280 Speaker 1: speed is reached. That's right. Um, what else, man, You've 249 00:14:29,280 --> 00:14:31,840 Speaker 1: got your environmental sensor, which will get into how all 250 00:14:31,880 --> 00:14:35,480 Speaker 1: this works. Um, But that is a device that tracks 251 00:14:35,520 --> 00:14:39,200 Speaker 1: airspeed and altitude. Um, it doesn't just shoot you up 252 00:14:39,240 --> 00:14:41,360 Speaker 1: and say I hope it's hope it's okay up there 253 00:14:41,920 --> 00:14:45,600 Speaker 1: right exactly? And then it also depending on the readings 254 00:14:45,640 --> 00:14:48,800 Speaker 1: it gets for your air speed and altitude, it'll it'll 255 00:14:49,240 --> 00:14:52,520 Speaker 1: trip like a certain type of sequence. So like if 256 00:14:52,520 --> 00:14:55,400 Speaker 1: you're at a very high altitude, there'll be a certain sequence. 257 00:14:55,400 --> 00:14:57,600 Speaker 1: If you're at a low altitude but going a very 258 00:14:57,640 --> 00:15:01,040 Speaker 1: fast speed, there will be a certain sequence, and so on. 259 00:15:01,480 --> 00:15:04,600 Speaker 1: And there's a car called modes of ejection. Well we 260 00:15:04,680 --> 00:15:07,480 Speaker 1: might as well go and cover that. It's Um, there's 261 00:15:07,520 --> 00:15:10,200 Speaker 1: something called and I had to look this up. It 262 00:15:10,240 --> 00:15:16,760 Speaker 1: was named for physicists Honree Peito, but um, everyone calls 263 00:15:16,800 --> 00:15:23,000 Speaker 1: them uh pedd or pidot tubes when it really should 264 00:15:23,040 --> 00:15:26,840 Speaker 1: be Peto tubes because he was French. But these are 265 00:15:28,280 --> 00:15:30,720 Speaker 1: when the when the sequence begin, it travels up the 266 00:15:30,800 --> 00:15:34,400 Speaker 1: rails and exposes these tubes and they measure air pressure 267 00:15:34,560 --> 00:15:38,720 Speaker 1: and the differences in pressure to determine like how fast 268 00:15:38,760 --> 00:15:41,400 Speaker 1: you're going and like which of these modes to enact 269 00:15:41,480 --> 00:15:44,160 Speaker 1: that we're talking about. So that that's the that's part 270 00:15:44,160 --> 00:15:46,240 Speaker 1: of the environmental center, and it sends that information of 271 00:15:46,320 --> 00:15:49,720 Speaker 1: the recovery sequencer, which is basically the chip that controls 272 00:15:50,000 --> 00:15:53,960 Speaker 1: the process. That's right. Um, So what are the three modes? Well, 273 00:15:54,080 --> 00:15:56,760 Speaker 1: there's low altitude low speed, which is less than two 274 00:15:57,160 --> 00:16:00,480 Speaker 1: fifty knots at less than fifteen thousand feet. No need 275 00:16:00,520 --> 00:16:03,800 Speaker 1: for a drug parachute. You barely even need an injection 276 00:16:03,840 --> 00:16:07,360 Speaker 1: seed at that point, you know. Um. There's mode too, 277 00:16:07,440 --> 00:16:10,920 Speaker 1: which is low altitude high speed for when you're like, 278 00:16:11,040 --> 00:16:14,200 Speaker 1: you know, Maverick or something like that, just going really 279 00:16:14,240 --> 00:16:18,960 Speaker 1: fast but low UM. And then there's high altitude any speed, 280 00:16:20,680 --> 00:16:24,520 Speaker 1: known as the scariest mode. Right. And so the modes 281 00:16:24,560 --> 00:16:29,080 Speaker 1: are all based on you'll notice two things altitude and 282 00:16:29,400 --> 00:16:35,720 Speaker 1: um speed velocity right. Um. And you put these things 283 00:16:35,760 --> 00:16:40,880 Speaker 1: together and you create a graph and inside the graph, 284 00:16:41,000 --> 00:16:46,920 Speaker 1: inside the the arc that's formed that's called the envelope, 285 00:16:47,520 --> 00:16:52,320 Speaker 1: and anything inside the envelope is um safety. Like it's 286 00:16:52,360 --> 00:16:56,320 Speaker 1: been proven, it's tested that if you follow this certain 287 00:16:56,360 --> 00:17:01,080 Speaker 1: sense of certain sequence of events for this mode, within 288 00:17:01,160 --> 00:17:04,359 Speaker 1: this altitude and this air speed, you're gonna most likely 289 00:17:04,440 --> 00:17:06,680 Speaker 1: be fine. That's right. If you go outside of that, 290 00:17:07,160 --> 00:17:10,280 Speaker 1: you are what's known as pushing the envelope. Is that 291 00:17:10,320 --> 00:17:14,160 Speaker 1: where that came from? That's awesome? It is. I thought 292 00:17:14,160 --> 00:17:17,440 Speaker 1: that was when you, like, we're super cool during negotiations 293 00:17:17,440 --> 00:17:19,359 Speaker 1: and you would just write down what you wanted and 294 00:17:19,400 --> 00:17:24,480 Speaker 1: push the envelope across the table. That's pushing your luck. Okay, wow, 295 00:17:24,680 --> 00:17:26,680 Speaker 1: I love that. You know me and word origins. Yeah, 296 00:17:26,720 --> 00:17:28,239 Speaker 1: I thought you'd like that when I saw it, and 297 00:17:28,240 --> 00:17:32,760 Speaker 1: I was like, Jack's gonna love it. So let's back 298 00:17:32,840 --> 00:17:35,879 Speaker 1: up a bit and uh start with with the bailout. 299 00:17:36,119 --> 00:17:40,160 Speaker 1: Your planes not doing well, you want to eject planes. 300 00:17:40,320 --> 00:17:43,720 Speaker 1: Not your plane is sick. You want to eject and 301 00:17:43,920 --> 00:17:46,360 Speaker 1: you pull the ejection handle. That sets off what we've 302 00:17:46,400 --> 00:17:50,119 Speaker 1: already talked about, that first explosion to catapult you up 303 00:17:50,119 --> 00:17:52,879 Speaker 1: the rails and into the air. And then there is 304 00:17:52,920 --> 00:17:58,240 Speaker 1: an under seat rocket motor that actually propels you even further. 305 00:17:58,320 --> 00:17:59,920 Speaker 1: And when you watch this thing in slow motion. It's 306 00:18:00,480 --> 00:18:05,840 Speaker 1: you know, serious rocket propelled action going on under your butt. Yeah, 307 00:18:05,920 --> 00:18:08,800 Speaker 1: and sometimes it's two stages, like the catapult and then 308 00:18:08,800 --> 00:18:11,960 Speaker 1: the rocket, but it's all in the same source. But yeah, 309 00:18:12,000 --> 00:18:14,760 Speaker 1: it's basically shot shooting you. So you go off on 310 00:18:14,800 --> 00:18:18,840 Speaker 1: a bullet and then a rocket. Yeah, that's what happens 311 00:18:18,880 --> 00:18:21,280 Speaker 1: when you're ejecting in like you said, within the first 312 00:18:22,000 --> 00:18:24,119 Speaker 1: half to one and a half seconds. Yeah, that's what 313 00:18:24,200 --> 00:18:27,280 Speaker 1: all this happens in the canopy obviously has been jettisoned 314 00:18:27,280 --> 00:18:30,120 Speaker 1: at this point, and that's a really cool thing to Like, 315 00:18:30,640 --> 00:18:33,480 Speaker 1: these things are have to functions canopy, so they're bolted 316 00:18:33,480 --> 00:18:37,000 Speaker 1: in there, and the way they're they're ejected as the 317 00:18:37,040 --> 00:18:40,640 Speaker 1: bolts are blown by little tiny explosive charges, right, that's 318 00:18:40,680 --> 00:18:43,840 Speaker 1: called lifting the canopy. Um, the bolts will blow and 319 00:18:43,880 --> 00:18:46,080 Speaker 1: the cannon people start to fly off, but then there's 320 00:18:46,119 --> 00:18:49,439 Speaker 1: another charge and another explosion towards the front that just 321 00:18:49,440 --> 00:18:52,560 Speaker 1: shoots it off in another direction away from you as 322 00:18:52,600 --> 00:18:55,240 Speaker 1: you're ejecting. All this is just so cool, man, how 323 00:18:55,280 --> 00:18:58,680 Speaker 1: fast it happens, how complicated it all is. Yeah, because 324 00:18:58,680 --> 00:19:02,040 Speaker 1: think about that, Like the computer sequencers still needs to 325 00:19:02,080 --> 00:19:06,400 Speaker 1: know what mode to follow, so like when that canopy 326 00:19:06,440 --> 00:19:09,040 Speaker 1: is starting to blow, it's taking the data readings and 327 00:19:09,119 --> 00:19:11,560 Speaker 1: deciding all this is going on in like a second, 328 00:19:11,560 --> 00:19:15,280 Speaker 1: a tenth of a seconded um. So lifting the canopy 329 00:19:15,359 --> 00:19:17,679 Speaker 1: is one way you can still become injured. You can 330 00:19:17,720 --> 00:19:21,359 Speaker 1: still run into the canopy, um I, just from blowing 331 00:19:21,359 --> 00:19:24,720 Speaker 1: the bolts. So there's another mode, um or another means 332 00:19:24,720 --> 00:19:27,320 Speaker 1: of getting rid of the canopy. And that's just shattering it. Yeah, 333 00:19:27,359 --> 00:19:30,880 Speaker 1: that's when it basically explodes. And uh, it's like you've 334 00:19:30,920 --> 00:19:34,560 Speaker 1: got chicken wire, but the chicken wire is explosive. Yeah, 335 00:19:34,720 --> 00:19:39,280 Speaker 1: just just evaporate. Yeah, well done, evaporate the slipstream. Just 336 00:19:39,600 --> 00:19:43,159 Speaker 1: makes it go by by really quickly. Um So for 337 00:19:43,200 --> 00:19:47,800 Speaker 1: all intents and purposes. Uh. And then we also mentioned 338 00:19:47,800 --> 00:19:49,639 Speaker 1: earlier if there is no canopy, there will be an 339 00:19:49,640 --> 00:19:52,760 Speaker 1: explosive hatch that basically that's the same thing that seems 340 00:19:52,840 --> 00:19:55,960 Speaker 1: the least safe to me, why because you can't see 341 00:19:55,960 --> 00:19:58,479 Speaker 1: through it. An explosive hatch makes me think of like 342 00:19:58,560 --> 00:20:02,760 Speaker 1: some really heavy thick steel that, yes, you can't see through, 343 00:20:03,400 --> 00:20:06,680 Speaker 1: and that is just really a hole in another bit 344 00:20:06,720 --> 00:20:09,439 Speaker 1: of heavy thick steel that you might bump into on 345 00:20:09,480 --> 00:20:12,480 Speaker 1: your way out, like like an escape hatch from a submarine. 346 00:20:12,760 --> 00:20:14,159 Speaker 1: That's what I think of when I think of a 347 00:20:14,200 --> 00:20:17,800 Speaker 1: hatch like that on a plane. You know, give me 348 00:20:18,000 --> 00:20:26,719 Speaker 1: a shattering canopy. You want it to dissolve above your head. Evaporate, evaporate. Alright, 349 00:20:26,720 --> 00:20:29,760 Speaker 1: So then once you're out from the rails, uh, that 350 00:20:29,800 --> 00:20:33,080 Speaker 1: secondary the rocket's gonna take you depends on your weight 351 00:20:33,160 --> 00:20:36,280 Speaker 1: A hundred to two hundred feet up to safe safely 352 00:20:36,320 --> 00:20:38,920 Speaker 1: clear you and um, I wish we had more recent 353 00:20:38,960 --> 00:20:43,160 Speaker 1: stats than this, but we have one from that said 354 00:20:43,160 --> 00:20:45,879 Speaker 1: that they had a success rate or I saw that 355 00:20:46,000 --> 00:20:48,680 Speaker 1: four d and sixty three injections. I saw that that's 356 00:20:48,560 --> 00:20:51,560 Speaker 1: a kind of standard for study from like I think 357 00:20:51,560 --> 00:20:53,440 Speaker 1: two thousand six or something like that, and they found 358 00:20:53,480 --> 00:20:56,479 Speaker 1: about eighty nine point four. And the bad news is 359 00:20:57,280 --> 00:21:00,760 Speaker 1: the other ten percent means you've probably died. Yeah, you know, 360 00:21:02,119 --> 00:21:05,640 Speaker 1: so it's either success or you die. Yes, I think 361 00:21:05,640 --> 00:21:09,080 Speaker 1: that's pretty much the I think saving your life through 362 00:21:09,160 --> 00:21:13,280 Speaker 1: the correct series is successful. Like if you're injured or whatever, 363 00:21:13,280 --> 00:21:17,720 Speaker 1: I think they still generally count that as success. Um. 364 00:21:17,840 --> 00:21:20,760 Speaker 1: So where are we man? So we're at the drug parachute. 365 00:21:20,760 --> 00:21:24,720 Speaker 1: The drug gun fires a metal slug and it pulls 366 00:21:24,760 --> 00:21:27,000 Speaker 1: out this little drug parachute. And then like we said, 367 00:21:27,000 --> 00:21:29,960 Speaker 1: then there's the secondary shoot that I think the drug 368 00:21:30,400 --> 00:21:35,840 Speaker 1: nnects that, right, yeah, the second they like the main shoot. UM, 369 00:21:35,960 --> 00:21:40,040 Speaker 1: so you get the main shoot out before this happens. Though. 370 00:21:40,760 --> 00:21:43,679 Speaker 1: Think about this when you are shot out on a 371 00:21:43,720 --> 00:21:47,000 Speaker 1: bullet and then on a rocket and you're going up 372 00:21:47,000 --> 00:21:50,880 Speaker 1: to I don't know, mark two, mark three, MAK one 373 00:21:51,040 --> 00:21:58,440 Speaker 1: is seven. UM. That's speed of sound like supersonic travel. Um. 374 00:21:58,600 --> 00:22:00,320 Speaker 1: And we have planes that can go a lot faster 375 00:22:00,440 --> 00:22:04,639 Speaker 1: than that. When you exit the plane like that, UM, 376 00:22:04,720 --> 00:22:07,479 Speaker 1: it's very easy for your seat to start to tumble 377 00:22:07,560 --> 00:22:10,800 Speaker 1: and move around and spin or your limbs. Let's say, 378 00:22:11,080 --> 00:22:13,719 Speaker 1: well we'll get to that. Just the seat itself. If 379 00:22:13,760 --> 00:22:16,840 Speaker 1: everything's going encoding, the plant plant can still tumble and 380 00:22:16,840 --> 00:22:20,160 Speaker 1: and this the wind resistance it meets can just push 381 00:22:20,160 --> 00:22:22,359 Speaker 1: it around in all sorts of weird angles. So there's 382 00:22:22,400 --> 00:22:28,399 Speaker 1: something called a Vernier rocket, right, and it's it is 383 00:22:28,400 --> 00:22:31,520 Speaker 1: a rocket that just kind of fires like um, remember 384 00:22:31,520 --> 00:22:35,640 Speaker 1: on Apollo thirteen when they were um like shooting off 385 00:22:35,640 --> 00:22:39,719 Speaker 1: the little booster rockets like need correct the yaw and 386 00:22:39,720 --> 00:22:44,280 Speaker 1: all that and pitch. That's what this rocket does. UM. 387 00:22:44,400 --> 00:22:47,879 Speaker 1: Or these rockets, I should say. It stabilizes the seat 388 00:22:48,160 --> 00:22:50,359 Speaker 1: and keeps it from spinning and tumbling and makes it 389 00:22:50,520 --> 00:22:54,280 Speaker 1: stay up and down exactly so it knows what it's doing, 390 00:22:54,440 --> 00:22:59,160 Speaker 1: just like your smartphone. Oh, yes, that what the compass 391 00:22:59,160 --> 00:23:03,160 Speaker 1: thing is. Yeah really well, I mean yeah, plus when 392 00:23:03,160 --> 00:23:06,080 Speaker 1: you tilted, it knows to go sideways. And yeah, I 393 00:23:06,119 --> 00:23:09,359 Speaker 1: mean I'm sure that or I hope the dejection seats 394 00:23:09,359 --> 00:23:13,959 Speaker 1: have a little more advanced systems. But yeah, gyroscope. Yeah, okay, 395 00:23:14,040 --> 00:23:17,760 Speaker 1: I never thought about that. Uh, maybe not a gyroscope, 396 00:23:17,760 --> 00:23:19,960 Speaker 1: but something that functions in that way. People are like, 397 00:23:19,960 --> 00:23:22,520 Speaker 1: that's not a gyroscope. We'll find out, Yeah, we sure, 398 00:23:22,520 --> 00:23:26,920 Speaker 1: well many times over. Okay, so Chuck, let's talk about 399 00:23:26,960 --> 00:23:29,680 Speaker 1: the physics of all this. Well, first we got to 400 00:23:29,720 --> 00:23:33,680 Speaker 1: cover the seat man separator motor. And that's actually once 401 00:23:33,680 --> 00:23:36,239 Speaker 1: you're in the air, you don't you're you don't want 402 00:23:36,280 --> 00:23:38,440 Speaker 1: you can't land in the seat. They wanted to get 403 00:23:38,480 --> 00:23:41,520 Speaker 1: you out of the seat, and that's accomplished by the 404 00:23:41,520 --> 00:23:45,400 Speaker 1: seat man motor separator. Yeah. This motor dease basically goes 405 00:23:45,440 --> 00:23:49,200 Speaker 1: we're and detaches the seat from you and you're you've 406 00:23:49,240 --> 00:23:52,400 Speaker 1: got your parachute one, You've got your survival pack still, 407 00:23:52,440 --> 00:23:54,359 Speaker 1: but the seat just kind of falls away to Earth 408 00:23:55,119 --> 00:24:00,760 Speaker 1: and you just um slowly parachute down and land and 409 00:24:00,800 --> 00:24:06,520 Speaker 1: if you're keptain scott O Grady, Yeah, then you spend 410 00:24:06,520 --> 00:24:12,000 Speaker 1: the next five days evading serbs. That's right, successfully successfully. 411 00:24:13,400 --> 00:24:17,720 Speaker 1: So physics my favorite topic. I know you love physics. Uh. 412 00:24:17,840 --> 00:24:20,440 Speaker 1: Newton's second law of emotion comes into play here obviously 413 00:24:20,560 --> 00:24:24,359 Speaker 1: because um force and acceleration of the crew member. Really, 414 00:24:24,560 --> 00:24:27,200 Speaker 1: you know, that's how you're gonna live or die. Yeah, 415 00:24:27,240 --> 00:24:31,399 Speaker 1: because when you exited plane, you get smacked by the wind, 416 00:24:31,720 --> 00:24:35,040 Speaker 1: that's right. I mean, you're going faster than the speed 417 00:24:35,040 --> 00:24:39,480 Speaker 1: of sound, and while you're normally operating the plane, the 418 00:24:39,520 --> 00:24:42,560 Speaker 1: plane's taking it on the chin for you. You're not 419 00:24:42,600 --> 00:24:46,080 Speaker 1: feeling this force of gravity nearly as much as you 420 00:24:46,160 --> 00:24:50,040 Speaker 1: are when you're no longer surrounded by the plane and 421 00:24:50,080 --> 00:24:52,920 Speaker 1: you're just exposed up there in the atmosphere. That's right. 422 00:24:53,440 --> 00:24:56,399 Speaker 1: So Newton's second law of emotion states the acceleration of 423 00:24:56,400 --> 00:24:59,080 Speaker 1: an object depends on the force acting upon it and 424 00:24:59,119 --> 00:25:02,439 Speaker 1: the mass of the object. Force equals mass times acceleration. 425 00:25:02,800 --> 00:25:06,240 Speaker 1: In this case, the mass is the mass of the 426 00:25:06,320 --> 00:25:12,400 Speaker 1: human pilot and the chair, right, and uh, the force Uh, 427 00:25:12,480 --> 00:25:16,520 Speaker 1: I don't know. Accelerations measured in gees right, So one 428 00:25:16,640 --> 00:25:21,400 Speaker 1: G equals the the amount of one the the amount 429 00:25:21,480 --> 00:25:27,760 Speaker 1: of the Earth's gravity right now, right. And so let's say, um, 430 00:25:27,840 --> 00:25:31,200 Speaker 1: let's say we're a hundred and eighty pound pilot at 431 00:25:31,280 --> 00:25:33,520 Speaker 1: sea level, we weigh a hundred and eighty pounds. That's 432 00:25:33,560 --> 00:25:37,800 Speaker 1: one g um when we're going t gs and so 433 00:25:37,880 --> 00:25:40,080 Speaker 1: on up to say twenty g s I believe, is 434 00:25:40,119 --> 00:25:43,640 Speaker 1: what the an ejection seat is like the best are 435 00:25:43,960 --> 00:25:49,560 Speaker 1: developed for At twenty g's hundred and eighty pounds, it 436 00:25:49,640 --> 00:25:54,719 Speaker 1: feels like thirty pounds. That's the force that you encounter 437 00:25:54,800 --> 00:25:58,280 Speaker 1: when you eject thirty pounds, All of a sudden of 438 00:25:58,400 --> 00:26:01,240 Speaker 1: force is being exerted on your body. Yeah, and keeping 439 00:26:01,240 --> 00:26:03,639 Speaker 1: in mind that one g of acceleration is equal to 440 00:26:03,680 --> 00:26:06,480 Speaker 1: thirty two per scond. Yes, And it all depends on 441 00:26:06,520 --> 00:26:08,199 Speaker 1: how much we weigh, like, that's how you figure out 442 00:26:08,280 --> 00:26:11,080 Speaker 1: the mass you in the chair. That's the big one. Also, 443 00:26:11,200 --> 00:26:14,480 Speaker 1: the the chair needs to know how fast to go 444 00:26:14,760 --> 00:26:16,960 Speaker 1: because it has to go slightly faster than the plane, 445 00:26:16,960 --> 00:26:19,640 Speaker 1: like I said, so it can clear it. That's amazing, Yeah, 446 00:26:19,760 --> 00:26:23,640 Speaker 1: it is. But when So when you reject and you 447 00:26:24,240 --> 00:26:27,560 Speaker 1: suddenly encounter twenty g s, which is the upper limits 448 00:26:27,560 --> 00:26:35,400 Speaker 1: of human Um, what's the word I'm looking for? Tolerance? Um, 449 00:26:35,440 --> 00:26:38,280 Speaker 1: A lot of really bad things can happen to you. 450 00:26:38,440 --> 00:26:40,080 Speaker 1: That's right, and we know this thanks for our buddy 451 00:26:40,119 --> 00:26:43,400 Speaker 1: Colonel step Yeah. Remember he used to have read outs 452 00:26:43,440 --> 00:26:46,959 Speaker 1: from the rocket sled and man he had some crazy 453 00:26:46,960 --> 00:26:50,600 Speaker 1: stuff happened to him. So what's the formula? UM speed 454 00:26:50,640 --> 00:26:56,680 Speaker 1: equals acceleration times time plus initial speed or v F 455 00:26:57,000 --> 00:27:02,240 Speaker 1: equals a T plus the I. Yes, So think about this. Okay, 456 00:27:02,280 --> 00:27:05,800 Speaker 1: what we just said is that, UM, we understand the force, 457 00:27:05,960 --> 00:27:09,280 Speaker 1: which is when you go up, you are suddenly exposed 458 00:27:09,320 --> 00:27:14,120 Speaker 1: to that lateral force, hit in the face with that 459 00:27:14,240 --> 00:27:20,280 Speaker 1: windy um, and you're also being pushed out and upward. 460 00:27:21,080 --> 00:27:24,160 Speaker 1: So I think you said that in some cases, within 461 00:27:24,200 --> 00:27:28,600 Speaker 1: the first second and a half you are up two feet, 462 00:27:29,960 --> 00:27:33,359 Speaker 1: So I think you said earlier something like you within 463 00:27:33,400 --> 00:27:36,639 Speaker 1: a second you are you go from sitting in the 464 00:27:36,680 --> 00:27:39,600 Speaker 1: plane to being up about two feet, So that means 465 00:27:39,640 --> 00:27:45,359 Speaker 1: you're traveling twot a second upward. So you're being pushed 466 00:27:45,400 --> 00:27:49,320 Speaker 1: up like that while you're being exposed to speeds of 467 00:27:50,040 --> 00:27:57,560 Speaker 1: upwards of seven twenty g's of force. UM. And all 468 00:27:57,600 --> 00:28:00,640 Speaker 1: of this is happening to your poor little body, so 469 00:28:00,720 --> 00:28:04,000 Speaker 1: a lot of really bad things can happen to it. Um, 470 00:28:04,160 --> 00:28:06,240 Speaker 1: first of all, First and foremost, I think the number 471 00:28:06,280 --> 00:28:12,040 Speaker 1: one injury from ejections is spine compression, oh man, Because 472 00:28:12,080 --> 00:28:15,320 Speaker 1: you're you're being pushed upward at a two ft a 473 00:28:15,359 --> 00:28:18,439 Speaker 1: second UM. That's a lot of force exerted on your 474 00:28:18,480 --> 00:28:23,080 Speaker 1: spinal column. So modern um ejection seats have things like 475 00:28:23,200 --> 00:28:28,720 Speaker 1: leg restraints, back restraints, restraints, and then that face curtain 476 00:28:28,760 --> 00:28:32,440 Speaker 1: restrain your head, and you were forced into a completely 477 00:28:32,560 --> 00:28:35,880 Speaker 1: up and down sitting position so that your vertebra are 478 00:28:36,200 --> 00:28:40,000 Speaker 1: stacked perfectly on top of one another, because any kind 479 00:28:40,000 --> 00:28:42,640 Speaker 1: of slip or any kind of angle leads to a 480 00:28:42,760 --> 00:28:48,120 Speaker 1: slip disc very easily. UM. And there's a long standing legend. 481 00:28:48,160 --> 00:28:51,440 Speaker 1: I couldn't verify that in the US Air Force, after 482 00:28:51,480 --> 00:28:55,320 Speaker 1: two or three ejections you're grounded for life because the 483 00:28:55,360 --> 00:28:58,760 Speaker 1: spinal compressions just basically used you up. I don't know, 484 00:28:58,920 --> 00:29:01,200 Speaker 1: I didn't see that it was true anywhere, but it's 485 00:29:01,200 --> 00:29:03,160 Speaker 1: an old legend. Well, at the very least, you're not 486 00:29:03,320 --> 00:29:05,920 Speaker 1: very good pilot, so they're like, yeah, maybe we should 487 00:29:05,960 --> 00:29:09,160 Speaker 1: around them. Or you're like three quarters your height that 488 00:29:09,240 --> 00:29:12,520 Speaker 1: you were when you enlisted because the final compressions, you know, 489 00:29:13,000 --> 00:29:15,440 Speaker 1: short now. So that's the number one I believe UM 490 00:29:15,600 --> 00:29:20,640 Speaker 1: injury that comes from ejection. There's also something with the 491 00:29:20,720 --> 00:29:25,760 Speaker 1: horrific name limb flail. So you're secured in your seat, 492 00:29:26,200 --> 00:29:29,000 Speaker 1: your arms, your legs, your head, you're supposed to be 493 00:29:29,040 --> 00:29:31,520 Speaker 1: totally immobile in that first couple of seconds, especially until 494 00:29:31,560 --> 00:29:36,200 Speaker 1: your parachute opens and you slow down and everything. If 495 00:29:36,280 --> 00:29:40,200 Speaker 1: your arm gets loose. Have you ever seen a dog 496 00:29:40,280 --> 00:29:43,200 Speaker 1: with its head sticking out of a car window on 497 00:29:43,240 --> 00:29:45,640 Speaker 1: a highway and it has real long, floppy ears, Yeah, 498 00:29:45,840 --> 00:29:48,200 Speaker 1: which is very dangerous. It's not something you should do 499 00:29:48,200 --> 00:29:50,840 Speaker 1: to your dog. It's bad for your dog. Developed cauliflowerer. 500 00:29:50,880 --> 00:29:52,640 Speaker 1: It's a bad thing to do. Get things in their eyes. 501 00:29:53,760 --> 00:29:58,360 Speaker 1: That's going like thirty to sixty miles an hour. We're 502 00:29:58,360 --> 00:30:01,880 Speaker 1: talking in arm a human r going more than seven 503 00:30:02,400 --> 00:30:05,200 Speaker 1: fifty miles. When it gets loose, what you have is 504 00:30:05,240 --> 00:30:09,600 Speaker 1: called limb flail, and what you have are completely shattered bones, 505 00:30:10,160 --> 00:30:14,720 Speaker 1: dislocated shoulders. Um, that's a bad jam. Or just imagine 506 00:30:14,720 --> 00:30:18,920 Speaker 1: going down the highway at like rolled on your window 507 00:30:18,960 --> 00:30:21,800 Speaker 1: and then quickly to stick your arms. Yes, yes, and 508 00:30:21,920 --> 00:30:26,160 Speaker 1: multiply that times you know whatever. Um, so that's another 509 00:30:26,200 --> 00:30:31,680 Speaker 1: type of injury limb flail. Um. There's wind blast, which 510 00:30:31,840 --> 00:30:35,520 Speaker 1: so they tested this on chimps of course, and um 511 00:30:35,560 --> 00:30:37,600 Speaker 1: it turns out that you can get third degree burns, 512 00:30:37,640 --> 00:30:41,760 Speaker 1: severe third degree burns just from the wind at um 513 00:30:42,040 --> 00:30:46,560 Speaker 1: mock one point seven. Being exposed to that peak one 514 00:30:46,600 --> 00:30:50,280 Speaker 1: point seven mack one point seven for one second can 515 00:30:50,320 --> 00:30:54,520 Speaker 1: give you severe third degree burns. Uh. And then there's tumbling, 516 00:30:54,880 --> 00:30:58,200 Speaker 1: which you might overlook, but think about this. Remember when 517 00:30:58,400 --> 00:31:05,680 Speaker 1: um know, the real math, No, the real life guys. No, uh, 518 00:31:05,240 --> 00:31:09,960 Speaker 1: the dude, oh man, No, the guy who jumped out 519 00:31:09,960 --> 00:31:14,800 Speaker 1: of the space capsule recently. You know the guy, yeah, 520 00:31:14,880 --> 00:31:20,200 Speaker 1: Felix bomb Gardener. Yeah, I can't believe I forgot that. Um. 521 00:31:20,400 --> 00:31:23,560 Speaker 1: The the when he jumped out, he started to tumble, 522 00:31:24,080 --> 00:31:27,040 Speaker 1: remember he started going in over end a first. No. 523 00:31:27,240 --> 00:31:29,360 Speaker 1: And the reason that that is really really bad is 524 00:31:29,440 --> 00:31:34,200 Speaker 1: because you can build up centrifugal force of your for 525 00:31:34,280 --> 00:31:37,720 Speaker 1: your blood and it pushes it outward to your extremities, 526 00:31:37,920 --> 00:31:40,520 Speaker 1: meaning your heart doesn't have any blood to pump any longer, 527 00:31:41,640 --> 00:31:44,120 Speaker 1: so you can die very quickly. I've seen between two 528 00:31:44,200 --> 00:31:49,000 Speaker 1: hundred and four hundred rotations per minute proves fatal to humans. Man, 529 00:31:49,880 --> 00:31:51,840 Speaker 1: how did that bomb grown? Your guy pull that off? 530 00:31:52,000 --> 00:31:55,880 Speaker 1: I don't know. That was pretty awesome. Yeah, and hey, 531 00:31:55,920 --> 00:31:58,120 Speaker 1: our own Discovery channel covered that live. Remember, Yeah, that 532 00:31:58,160 --> 00:32:00,360 Speaker 1: was huge. It was very cool. That first shot, Dude, 533 00:32:01,000 --> 00:32:03,120 Speaker 1: I like, I can't look at that when it just 534 00:32:03,200 --> 00:32:05,480 Speaker 1: falls out of it at his perspective shot when he 535 00:32:05,600 --> 00:32:08,360 Speaker 1: was just like all right, I'm jumping out of something 536 00:32:08,400 --> 00:32:11,360 Speaker 1: from space. Yeah, that was amazing. I remember, um, you, 537 00:32:11,440 --> 00:32:12,920 Speaker 1: me and I were coming back from some trip or 538 00:32:12,920 --> 00:32:15,360 Speaker 1: whatever and we just happened to be in the airport 539 00:32:15,680 --> 00:32:18,040 Speaker 1: when I remembered it was going on. I'm like, oh, yeah, 540 00:32:18,040 --> 00:32:20,880 Speaker 1: we should watch this, and ended up standing there watching 541 00:32:20,920 --> 00:32:23,000 Speaker 1: like one of the most amazing things I've ever seen 542 00:32:23,040 --> 00:32:25,120 Speaker 1: in my entire life. Yeah, I mean, that was just 543 00:32:25,160 --> 00:32:27,280 Speaker 1: an amazing thing to see. Yeah, and I bet you 544 00:32:27,400 --> 00:32:29,680 Speaker 1: he wants to top it. I'm sure he's like high 545 00:32:29,720 --> 00:32:32,240 Speaker 1: or still. Yeah. And do you remember the guy who 546 00:32:32,240 --> 00:32:35,240 Speaker 1: did that in like the like nineteen sixty or the 547 00:32:35,800 --> 00:32:40,160 Speaker 1: late fifties. Oh, he did it like in this exposed 548 00:32:40,360 --> 00:32:44,040 Speaker 1: weather balloon wearing like a high altitude a halo mask 549 00:32:44,160 --> 00:32:49,960 Speaker 1: and air supply and everything, and you've seen footage of it, yes, 550 00:32:50,400 --> 00:32:52,640 Speaker 1: but he ended up being like the whole program director 551 00:32:52,680 --> 00:32:56,040 Speaker 1: for Felix baum Gardner's jump, Like he tapped him because 552 00:32:56,040 --> 00:32:58,040 Speaker 1: he's the only other guy who's done anything like that, 553 00:32:58,640 --> 00:33:00,600 Speaker 1: and this guy did it in like the eight fifties, 554 00:33:00,600 --> 00:33:02,840 Speaker 1: I think, so he was literally the only person he 555 00:33:02,880 --> 00:33:05,880 Speaker 1: could say, what's it? Like? Manly? He said, it sucks 556 00:33:06,000 --> 00:33:08,200 Speaker 1: and it's awesome. Apparently he had like a hole in 557 00:33:08,240 --> 00:33:10,640 Speaker 1: his glove or something like that that they had he 558 00:33:10,800 --> 00:33:13,280 Speaker 1: told them back on the ground what was going on, 559 00:33:13,600 --> 00:33:16,200 Speaker 1: they would have called off the mission. And no, the 560 00:33:16,280 --> 00:33:22,640 Speaker 1: other guy and he just didn't tell him. So that's 561 00:33:22,640 --> 00:33:27,040 Speaker 1: how Felix bond Gardner works. Alright, Ejection Seats, you've got 562 00:33:27,040 --> 00:33:28,840 Speaker 1: anything else? I don't have anything else. Yeah, that one 563 00:33:28,880 --> 00:33:31,680 Speaker 1: was really cool. I thought, Yeah, very complex thing going 564 00:33:31,720 --> 00:33:35,000 Speaker 1: on very quickly, and watch that super slow mo and 565 00:33:35,040 --> 00:33:38,680 Speaker 1: then it shows it in regular time. It's pretty neat. Okay, 566 00:33:38,680 --> 00:33:41,000 Speaker 1: So since we don't have anything else, um, we would 567 00:33:41,040 --> 00:33:44,160 Speaker 1: advise you to go onto the how Stuff Works website 568 00:33:44,160 --> 00:33:46,600 Speaker 1: and check out ejection Seats. Type that into the search bar, 569 00:33:46,640 --> 00:33:49,000 Speaker 1: and since I said search bar, it is time for 570 00:33:49,160 --> 00:33:54,960 Speaker 1: listener mail. Yeah, I'm gonna call this b FF. Hey, guys, 571 00:33:55,000 --> 00:33:58,840 Speaker 1: I've been listening for about six months and catching up 572 00:33:58,840 --> 00:34:00,920 Speaker 1: on most of your old shows. In that time. I 573 00:34:00,960 --> 00:34:04,400 Speaker 1: was introduced to your podcast by my best since sixth 574 00:34:04,440 --> 00:34:07,640 Speaker 1: grade friend, who was also a serious fan. I admit 575 00:34:07,680 --> 00:34:09,400 Speaker 1: that it took me a few episodes to warm to 576 00:34:09,400 --> 00:34:12,160 Speaker 1: your podcast, and now I feel a bit cheapish for 577 00:34:12,239 --> 00:34:15,799 Speaker 1: ever doubting my friends recommendation. Not only is she one 578 00:34:15,840 --> 00:34:18,239 Speaker 1: of the smartest people I've ever met, She's one of 579 00:34:18,239 --> 00:34:20,759 Speaker 1: my oldest friends. It knows me better than anyone. We 580 00:34:20,840 --> 00:34:22,759 Speaker 1: have a long history of directing each other to many 581 00:34:22,800 --> 00:34:26,280 Speaker 1: fabulous and geekye pursuits, but stuff you should know, maybe 582 00:34:26,320 --> 00:34:28,439 Speaker 1: the best of them all. And I have to say, 583 00:34:28,600 --> 00:34:33,760 Speaker 1: stiff competition. You're up against Tolkin, the X Files, Star Trek, 584 00:34:34,239 --> 00:34:38,920 Speaker 1: epic rat battles of History, Dune. She says, we talk 585 00:34:39,000 --> 00:34:43,040 Speaker 1: all of those. Wow, I mean I see the rat battles, sure, 586 00:34:43,840 --> 00:34:47,920 Speaker 1: Dune maybe, but tolkan X Files Star Trek.

People are gonna be shocked. 589 00:34:54,200 --> 00:34:56,959 Speaker 1: I've never seen a single Star Trek episode in my life. 590 00:34:56,960 --> 00:34:58,600 Speaker 1: I think I did when I was a kid. Now, 591 00:34:58,840 --> 00:35:00,920 Speaker 1: I'll bet I would like it as an adult now. 592 00:35:01,040 --> 00:35:04,439 Speaker 1: And I saw the Wrath of con Yeah, I saw 593 00:35:04,480 --> 00:35:08,880 Speaker 1: that finally.

Uh. It's it's 601 00:35:35,239 --> 00:35:37,000 Speaker 1: not that I think there should be a wall. I 602 00:35:37,040 --> 00:35:39,520 Speaker 1: just never got into Star Trek as long as it's 603 00:35:39,600 --> 00:35:42,120 Speaker 1: you're not hating on Star trekah, No, of course, not 604 00:35:42,360 --> 00:35:46,840 Speaker 1: ak trick.
