Chunder, I've read an account of a US pilot's only flat spin in his service career, whilst on a training flight in a P-39. He blacked out during a dive pull out, and came to at the top of the zoom in a flat "syscamore leaf" spin. After fighting it as long as he could, he started to bail. He opened the door (he didn't "eject it or anything); and as he did so the plane started to come round.
He's always thought that maybe the car type door flapping in the wind made just enough difference to the aircraft attitude.
