I used to do that.
In initial pilot training there was a bunch of academics and hands-on training related to ejection and parachuting.
We practiced the physical actions many, many, dozens of times over a few weeks to burn them into your head. A normal part of military flying is also memorized procedural steps for a few, say 5 to 10, very urgent emergencies. Each aircraft type has their own set of emergencies and aircraft-specific steps, but ejection is one of them on any aircraft so equipped. You’d have a written test daily on the entire set and a single word misspelled or hyphen out of place was a big deal. The minimum accepted standard was total perfection.
We fired ourselves out of a mockup cockpit on a simulated ejection seat that was a real seat but powered by compressed air like a catapult. It launched you and the seat some 20 feet up a rail & then the mechanism lowered you back down gently. Sorta like some extreme amusement park rides are now.
It was not as violent as the real thing, but it was a lot more violent than an amusement park ride.
We also did a sort of hybrid parasailing where we tow-launched behind a boat or a pickup truck using a real seat parachute & then disconnected when a couple hundred feet up and did the final descent & landing for real. Seat parachutes are not nearly as steerable or slow-descending as modern sport 'chutes even back in the 80s when I was doing all this. Landings where / are pretty harsh.
So that’s initial training. Whenever you’d change aircraft types you’d learn the new emergency steps and practice the motions in an inert high-fidelity mockup a couple dozen times over a couple weeks.
Once out in ordinary squadron service you’d get retrained / retested on all this every 6-9 months. Sit through a couple hours of refresher live lecture & video, on everything about using the seat and the parachuting & landing which (if you were lucky) followed. Then go through all the motions for ejecting, parachuting, and landing in various mockups. In trees. In water. In flat terrain. Against cliff faces. At night. And in combat versus in peacetime.
Also, the daily written emergency procedures test continues throughout your flying career, so the steps for engine fire, takeoff abort, and yes, ejection, are pretty well burned into your head. I flew 4 different types in my 8+ years. The last was 23 years ago. I bet could still get about 50% on all 4 tests, not having thought about any of it since then. Burned in. Burned in deep.
Finally, as a profesional whose life is on the line every time you hit the start switch, you rehearse these things. At sometime during the start, taxi, and wait for takeoff process, you go through a ritual of mentally repeating the verbal steps & miming the actions for takeoff abort and for ejection. Move the hands, touch the switches or controls, arrange the head & neck & feet. And do it all at real time speed. With that mental and physical preparation, it takes about a 2/10ths of a second to go from *decision made *to *seat actuated *and then (hopefully) all the magic is doing its work. If all goes well, about 1 second after that you’ll be a couple hundred feet away from the airplane under a rapidly opening parachute. If you were close to the ground, you’ll have a few seconds at most until landing/impact. Better be sharp.
As an aside, much of the airline biz approaches takeoff aborts in a similar fashion. Mentally & physically rehearse an abort before each takeoff, because this one just might be your (un)lucky one, and you’ll have almost no time to get it right, and a lot of ways to get it pretty spectacularly wrong. Film at 11.
Historically, most pilot losses in ejection seat aircraft come from either fundamentally unejectable situations, or the pilot delaying the decision to eject until a good opportunity degraded into no opportunity as the fire got worse or the altitude lower or the vector more inverted, or the gyrations more chaotic, or …
So a significant part of the training is about getting to the mindset that jumping out is a good end to a bad situation. If the situation is bad & about to get worse, bail. It’s not a personal failure or admission of cowardice or weakness. Yeah, we’d all like to bring the jet home every time. But if it’s bad & about to get worse, pull the handle & give the jet back to the taxpayers.
Note I said “bad & *about to get *worse”. Bad & actually *getting *worse is usually too late.
As I sit here today, I think that sums up a lot about flying, and fighter flying in particular.
Flying is all about accurately predicting what the situation will be in 5-60 seconds and doing *now *what will have been needed by then. The faster & more dynamic the environment, the harder it is to accurately see farther and farther into the future. But the more necessary it becomes. Folks crash or get shot down when they can’t accurately see well enough, far enough, into the future. And then that future arrives in the form of an explosion or terra firma. Which is why most pilots’ last words & thoughts are surprise, not resignation.
