A big issue with ejecting is getting the parachute open with plenty of time before landing on the ground. In the past, sufficient altitude gave the parachute time enough to open enough for a safe landing. Airspeed obviously provided an assist in the form of wind to help open the 'chute.
However, many ejections are at fairly low altitudes (especially in the Navy, as a result of carrier operations), so a means to help ensure safe escape at lower altitude and lower speeds was needed.
In the Navy (maybe the Air Force too), an ejection seat parachute has 28 riser cords. These are all bundled together where they attach to the canopy itself, and 14 small explosive charges are incorporated into the bundle. When the seat is fired, the automatic timing sequence handles a bunch of chores in quick succession. One of the last timed events is the firing of the 14 charges, which forcibly opens the canopy, helping it to fill with air much more quickly.
As a result, it's fairly safe to eject in a parked airplane (unless it's parked in a hangar, and that's happened, much to the chagrin of the crew that had to clean the hangar ceiling).
The Russian seats (the Zvezda K-36, I guess?) ALSO will compensate for far off-axis ejections, and can actually right the seat from a really bad shot, possibly close to inverted.
One thing I forgot to mention is that the ejection in the video could have been accidental. Fire may have set off the rockets, or possibly a piece of wreckage could have activated one seat. Typically in multi-crew aircraft, command activation (one pull of the handle shoots everyone) and self activation (each man for himself) are options, so if the pilot's seat went off, the other might follow automatically.
I'm dense today. An addition to my addition. Some seats are designed to fire a few few underwater, and in some cases this has actually happened, saving the crew. The seat goes right through the canopy. In fact, some aircraft are designed for ejections through the canopy.
In the recently retired S-3 Vikings, for instance (my aircraft), the four-person crew would eject through the canopy. The seats were equiped with "breaker bars" that stuck up about 10 inches above the rest of the seat in order to break the canopy before anyone's head did. The canopies also had explosive detonation cords for quick removal, but that was a manual process and not really intended for ejections.
More trivia. Seat cushions on ejection seats are very thin, maybe a half inch or so. The reason for this is that the acceleration is so great that if they gave you much more padding, the seat would have reached too high a speed before fully compressing the foam, and the occupant would be at risk of a broken pelvis, etc. from the impact. So by using a thin cushion, the butt accelerate with the seat, preventing the seat from accelerating into the butt.
@realsnickers: No, my dates love my "corporate accouting rules" small talk, especially when I get to the part about naughty boys who break the rules. Oh yeah, they like it then. ;)
@zenpoet: Because I could not stop for Death, He kindly stopped for me; Because I was but a second late, in my eject button pushing spree.
The airplane held but just ourselves And Immortality. We slowly drove, he knew no haste, And I had put away My parachute and flight stick too, For his civility.
This kind of video format SUCKS the way it is embedded, the progress bar blocks the play pause button and it just jumps back to the beginning when I try and pause it so it can load before I watch it. Even waiting a long time and clicking the replay button that pops up big on the video once it finally ends doesn't work as the WHOLE VIDEO RELOADS. Using safari, and when i click through the link, flight global managed to embed the liveleak video just fine. GIZMODO FAIL!!!!!!!!!! PLEASE RESEARCH HOW FLIGHT GLOBAL EMBEDDED THE VIDEO AND LEARN FROM IT.
@Chris Karash: Same problem here. I generally just skip these videos because I have to hit the play button 47.3 times before the stupid thing plays, and I don't just hear sound.
@Chris Karash: I use Mac + Safari too and I can confirm video embeds and (especially) galleries have always sucked to high hell on Giz, which is ironic if nothing else.
Most ejection seats are designed for zero/zero (zero altitude, zero speed) conditions. I mean... if you're strapped in and need to get out of a burning airplane, there really isn't time to do anything BUT eject.
@mushroom_mushroom: Most modern ejection seats can sense their altitude/orientation, and eject the pilot almost no matter what, even inverted.
There is one I couldn't find of a jet hitting the ground almost vertical and the pilot ejecting safely, even as the plane goes nose first into the dirt. If anyone can find that one....
@mushroom_mushroom: It's more dangerous if during a training exercise, the radar officer in your F-14 tries to eject but the hatch doesn't open, causing him to slam into it and die. Then, you are so traumatized that you go into a depression and become emotionally distant from everyone, even the hot flight school lecturer that you are banging. Sure, you might pull yourself together to graduate with the rest of your Top Gun class, but is it really worth losing the best pilot trophy to a douchey but disturbingly-sexy Val Kilmer?
@Hello Mister Walrus: Actually, the "hatch" is a canopy. And it doesn't "open" during an ejection, it's blown up and away from the fuselage. Unfortunately, when the F-14 is in a flat spin, as was Maverick and Goose's, it creates an odd pressure area that causes the ejected canopy to just sorta "hang" right above the cockpit for a second before it clears the aircraft. That's why Goose struck his head.
That part of the movie was suggested by the Navy after the filmmakers said they wanted Goose to die in an air-to-air collision. The Navy said NO WAY are you gonna show our guys involved in an air-to-air. They were asked to come up with a scenario in which Goose could get killed. Based upon an actual training accident in the early days of the Tomcat, they came up with this scenario.
You know as an avid biker, I have never had a problem with my ass getting cold. Now maybe falling asleep, but then I wouldn't be able to feel how much this thing is burning the shit out of my ass.
I guess if your old a duel purpose would be to iron the wrinkles out of your ass! lol.
