But that's what a stuntman from Oxfordshire did in what is being hailed as aviation history: Gary Connery, 42, became the first skydiver in the world to land without the use of a parachute.
And you can watch it right here:
Connery jumped from a helicopter a mile above Henley in a wing suit and glided down toward a "runway" of 18,000 cardboard boxes, where he landed.
"It was so comfortable, so soft," Connery said in the YouTube post. "My calculations obviously worked out and I'm glad they did."
His wife Vivian said she was "relieved it's all over."
Until the next stunt, that is.
