It's the same with base jumping. I remember watching a documentary on it one time and almost all of the people being interviewed knew multiple people that died during a jump.
In mountaineering, if something goes wrong, you could die.
In base jumping, if you don't do everything correctly, you will die.
A bit like the difference of a car engine failing (it will roll to a stop) vs an airplane engine failing (you will come down hard on the ground)
Or that almost suicidal thing with the wingsuits some people do: I get the appeal, I'm sure the rush of feeling like flying must be incredible, but they are playing Russian roulette.
It might have been true for the pioneers of the sport though.
It's more dangerous than jumping from a plane with a wingsuit.
I read the fatality comment somewhere presumably somewhat authoritative but it was a while back.
hehe a friend wants to do it. He has a trainer. The condition was at least 5000 jumps from plane with parachute . then 3 years training with at least 1000 or more jumps from plane or so….. it was hard and demanding be asured. he is elite lvl in sport. i wouldn’t do it. not because of the danger but because the training to do it safe is to hard.
