Frankly, that would be an enormous thrill.
In order for me to do it I'd have to jump out of a plane at about 10,000 feet and try to get familiar, then open a 'chute.
Do that about 5 times, maybe 10, and one could do it in the mountains.
It seems they have a glide ratio of 3, maybe 4 to 1, have to land by a parachute. It's a pretty steep fall. Your basic light plane, for instance, has a glide ratio of 7 to 1, as do some fighter planes. The problem with fighters is that they are going so fast they travel that quite rapidly.
Looks like a huge thrill. I've had dreams of doing the same thing.
