Where's My...oh, Nevermind.
Once around the flag pole is not what we had in mind. And I will keep calling this blog Where's My Jetpack? until these things are more compact, cheaper than Segways and available at WalMart.

technically speaking, the video is for a compressed-gas rocket. A jet actually has to receive air and then expel it at a higher velocity. It all works on on of Newton's motion laws, action-reaction. A typical general aviation airplane moves thru the air due to the large amount of air the prop is sending rearwards, same with a jet engine. A rocket engine is a jet engine with no air intake, using a liquid oxygen for the air burned. If no air is being drawn in for the burn/accelleration process, I would have to call it a rocket pack
