Before you ask:
60m off a viaduct in Normandie, several times, good for a laugh but a bit quick
190m off a tiny meccanno (ish) suspension bridge, down a ravine, Sierre Switzerland, couple of times, fantastic!
300m out of a cable-car in Leukerbad Switzerland, once, great
400m out of a helicopter in germany. Actually less fun than the ravine, but Looooooooong, there's not many sports where you can equal the world record with so little training!
Anything more than 100m I'd reccommend to anyone. Anything shorter and it's all a bit quick and violent. 60m I'll put up with, 50 or less I'd rather not. Cranes, forget it.
Safety? These aren't amateurs tieing some spare elastic around a post and chucking you off, these are professional commercial sites with trained jump-masters, professional equipment (strong enough to bungy a car, let alone a human), they weigh you and know precisely where you're going to end up - the normandie site even asks you if you want to get wet in the river below, and if so, HOW wet, and they can calculate it to within inches. The safety record of these places shows you're WAY more likely to get hurt on the road on the journey there than you are in the jump itself.
