This particular test was unmanned (that's Jetson, a dummy/counterweight, that you see up there), though we've already seen the jetpack take a real pilot upwards at Oshkosh back in 2008. But that was a short and highly controlled hover. To be honest, that flight was pretty conservative, though the idea at the time was only to prove the concept publicly. The flight in the video below, controlled by a pilot on the ground, is the real deal, showing that the jetpack can sustain flight over a period of minutes. With this success, surely longer-duration flights are in the offing.
