There have been "rocket belts" since the 60's, and one was featured in a Bond movie. They used a rocket propulsion system, I'm sure Brett can explain the fuel and how it worked, but it had a very limited burn time. I have seen these fly on TV at Super Bowls, Disneyland and such. This system is pure jet propelled, probably runs on JP-4? Probably a much safer system, if you can use that word. I got to see the guy that had a strap on set of wings with four small turbine engines strapped to it at Oshkosh a few years back. He jumped out of an airplane, lit the engines and could cruise around and even gain altitude, but had to launch from an airplane and recover by parachute. This system looks like a lot more fun, and like I said before, a "safer" system if that is possible.
Type at you later,
