Here's another cool find: Airscooter
Check out the Airscooter II, it looks like a personal helicopter for roughly the cost of an SUV.
There's no firm release date yet (some time in 2005), but it looks impressive so far.
If this thing became popular they'd have to re-write alot of laws, I think. Just think of a sky full of these things. They'd probably have to change the rules on unlicensed flying to exclude this thing. They might even have to come up with a completely different system of air traffic control...
