What I don't understand is why jump planes don't have a front door jetison system
I heard a story from one of the original GA8 airvan test pilots that he had to jump out of one whilst doing CofG testing. Apparently because of the way it was spinning he jumped out the door and ended up sliding forward along the body and up over the engine cowling, through the prop arc and ended up on his back hurtling towards the ground with an airvan directly overhead! Thankfully he shut the engine down before exiting otherwise the prop would have chopped him up.
Magnified bar story? maybe. Makes you think twice about jumping out of an out-of-control airplane though.
