You HAVE TO BE INSANE to jump off a skyscraper. Plus- doing flips? Dumbest thing I've ever seen. Why?? Because I'd be the guy that pulls the ripcord while upside down, which would deploy the chute - which would then wrap around me and plummet me to my death.
No way, Jose.
BUT......this guy is good at it... so - its pretty cool.
The old dude, he lands next to is as chill as can be though..
