Now THAT’S a Freakin’ Jet Pack!

It’s always annoyed me that the term “jet pack” is used when the device in question is usually, technically, a liquid fuel ROCKET pack. It’s not exactly clear what technology Yves Rossy is using (“Fusionman,” as he’s called when he dons his wings, is tight-lipped on the details), but it *is* clear these are jet engines, four of them. The gorgeous, foldable wings are carbon composite. He has logged some 30 flights with the jet wing and can go for up to six minutes and travel at a speed of 100 knots (over 115MPH).
