They do have a way to come in for a landing without a chute. It's called a crash landing or instant death.
At one time it was called a "bounce"; probably still is.
Those folks are extreme.…what a gas! Landing your jumpsuit would be a trick! You would surely be reminded of the ½” rule if you managed to pull it off. The wingsuits were banned in the late ‘70’s and ‘80’s; although I can’t remember why….I think that I used to know why but I can’t remember that either.
The 40 way shot above was taken over Zyphyrhills, Fla. in ’85, out of a DC3 called Southern Cross. Back then a 40 way was a big deal, today not so much; still a hell of a lot of fun, though!
