This is "Jet-Man". Former pilot, he's taken four scale model sized turbine engines (usually used to power remote controlled models of f-16's and such), bolted them to a foldable wing he straps to his back, then he jumps out of an airplane. Yeah. Landing? Cut the power, pull your chute.

There is a video on his site you just have to see, apparently he gives performances too.

Go see him fly

Here.
