As a chopper pilot who supported air assault operations, I should point out that jumping & rappelling are controlled descents carried out by trained personnel under supervision.
Falling off a roof is not a controlled descent.
And although I have slipped the surly bonds of earth and danced the sky on laughter-silvered wings, I am scared to death of going up on the roof, which I had to do when I sold a couple of old downtown buildings a while back.
Scaling a 25 ft ladder while remembering not to look down....geez!
;^)
The old style Swiss seat rappelling was not very safe, the SAS didn’t like us using that old fashioned method, and sure enough, one of them crashed and burned with us, he lived, but was out of the military.
I have been in the cockpit of a commercial airliner, but I think that sitting up front in a helicopter would exhaust me in about 10 minutes.
By the way, multiple jumps in a day used to do that, I guess the exhaustion comes from having to deal with the internal stress and adrenaline.
