All I want to know is, why, in 20-friggin-10 I still don't have one? They were supposed to be all over the place by the dawn of the 21st century. At least that is how I recall the predictions of gasbags like Walter Cronkite, back when I was a wee lad in 1965.
My dream of being killed at relatively low speed, from 20' above ground, is still unrequited!
Perhaps Jetson cars will be available soon. Yet another unrealized futureworld predicton...
Not truly a jet, but a ducted fan. Running on a 2 stroke V-4. The old rocket belt only had a flight time of about 20 seconds. No moving parts, no flame, but no flight time, and fuel not readily available. Know a couple guys that made a bigger version of rocket engine for a riding lawn mower.
True jet pack would have real jet engines, and be smaller.
If you are seeing the vid for the first time, then you may be behind the times.
