Yo BOAC!
I have many friends that had the experience of being in free fall after being hit by AAA or a SAM. One guy told us that first thing he saw was no "floor" on his jet.
It's the luck of the draw.
Most of us had a barometric doofer that deployed the chute at 14,000 feet or so without any action on our part.
The biggie is being ejected from the wreckage via a system or blind ass luck. I would take either, heh heh.
