> thought I'd jump in on this one. I've been a Stearman driver for about
30 years and might have about as much time in "unusual attitudes" as right
side up. In a fully developed spin, the door on the outside of the spin
will be pretty difficult to open, and in fact it's tough to even move
yourself out on that side. the old military training in open cockpits was
to bail to the inside of the spin if unrecoverable. so, the quick release
pins are in the aerobat to ensure you can get the door off- Centrifigal
force and wind presssure will keep it closed otherwise.
