Incredible videos of skydiving, jetpack rides and other insane tech-aided extreme sports are pretty much a staple for us - but we've never seen anything quite as cool as this retro-tech enabled stunt.
Erik Roner recently teamed up with GoPro to record himself jumping out of an aeroplane with an umbrella.
That's right - Roner used the stunt to prove that - for a while at least - it's possible to use a very big umbrella to slow your fall in mid-air, Mary Poppins style.
Unfortunately the umbrella eventually broke, and Roner had to use his parachute.
But he did manage to sign off with a pretty decent one-liner.
"You're welcome, science!" he said. Take a look, above.
