We might be getting into semantics here, but according to the makers of this video (and the Jetpack), this is the first “true, untethered Jetpack” flight.
There have been many back-mounted flying contraptions that loft a human skyward since the 1970s. However, they weren’t jets, or they were too heavy to be carried on the pilot’s back when fully fueled.
This one is. The JB-9 by Jetpack Innovation is the real deal, powered by two state of the art turbine jet engines that have been specially adapted to carry a human pilot aloft from the ground after many years of development and testing.
The JB-9 is the smallest and lightest JetPack ever created and the only Jetpack ever built that can be carried on the pilot’s back with relative ease – even when fully fueled.
