[ame=http://www.youtube.com/watch?v=0snTqLQLpBA]YouTube - JetLev-Flyer Water Jet Pack Facts[/ame] how awesome would it be if you could just use these at theme parks?
It would be pretty sweet, but you need to be trained to use them unlike a theme park where you just strap in and have fun. People could get SERIOUSLY fucked up using these at a theme park, such as flying sideways out onto solid ground and splatting into the pavement going 40mph.
they could modify it so that you can only fly around a certain radius and there could be like safety ropes attached from the jetpack to some support beams higher up..
