With all those fantastic prospects, yet we haven't seen a single one prototype, be it on battleship or other platforms.That is why I am getting suspicious that the whole thing might never works and just was another governmental hoax like the "starwar plan", which never meant to have a practical goal.

So you mean that the jetpack is just for the Olympic game showcase? What a disappointing! I thought it would be kind of cool if we can have a new form of sport with it. Sigh...
