It's a fucking base jump! And judging by your post it sounds like you know nothing of base jumping.

It is nothing like just falling in the air, then pull the chute and land safely. You've got to understand that the mechanics of a base jump is completely different from a skydive. When base jumping it is imperative that you get into the proper fall right away - you cannot correct your fall like in a skydive where there is plenty of time to get ready to release the chute. When you do a base jump you don't just "simply pull the chute", because if you are tumbling through the air when you pull the chute, there is a high risk of entaglement followed by flat death.

But you go ahead and tumble off a cliff like that with a chute - i'll happily film, then we'll see who's still alive afterwards.
