OK, so this is all over the news, but it's kewl.
I think the video looks like science fiction.
It's actually a lot like the Green Goblin's foot-rocket-flier in the old Spiderman comics. It's surely fast enough, despite not having a back-pointed rocket like ol' green-face's device, it seems it can go 150km per hour! Dang, that's faster than I've ever gone in a car (and presumably faster than most people have gone, since I believe it's only in Germany you can go that fast on certain roads).
Article on the Verge.
The inventor/company says it can reach a height of over 3 kilometers. Personally I'd bring a parachute.
