Re: This needs to be standard issue
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.
