Back in the 1950s and 60s my dad was a parachute training instructor for the RAF. As well as teach others how to safely jump out of planes, he also basically did QA for ejector seats.
His service ended when one such seat really wasn’t ready for humans. It totally fucked his back up — he didn’t become wheelchair bound, but was told to never lift anything heavier than a cup of tea for the rest of his life. Registered disabled from his mid-30s. Ejector seats were, and I assume still are, no joke.

Earlier seats had speed and/or altitude requirements. Presumably this means that they kick you harder too, with all such subsequent effects.
- robonerd 4y agoMany early ejection seats used explosive charges instead of rocket motors. These were less powerful overall (didn't throw pilots as far from the plane) but I suspect they might have kicked a lot harder in the instant of ignition.
- rich_sasha 4y agoInteresting... it sounds familiar with various videos of ejection over time, but I never realised this changes the force dynamics!
- kayodelycaon 4y agoModern ejection seats have a smoother acceleration curve than the early ones.
