Jetpack flies at AirVenture
Today this jetpack was demonstrated at EAA AirVenture. It seems like the closest thing yet to one that is actually marketable: it has flown a demonstration flight in public, and a CNN reporter was able to handle it after minimal training. Rather than a finicky rocket that burns hydrogen peroxide, it uses a gasoline V-4. It's also considered an ultralight, which means very minimal regulations.
Darn it, I could have gone to AirVenture, and I decided not to this year!
