Interesting

I like the videos, looks real..dunno if it would be really sucessful or not tho soon.
Yea, they had some kinda discovery channel thingie on that a year or so back. It is real, and they showed it taking off and stuff on there.
The biggest problem with this is that they are planning to have it all automated. You put in the destination and it will do the routing and flight plan all by itself. That's great and all, but it comes down to infrastructure. Where will you park them? how will you interface with road-based traffic? What kind of system (centralized? distributed?) are you going to have to communicate with all of the cars to prevent midair collisions? Are they classified as road-going vehicles or airplanes? do you need a seperate license? what are the insurance policies?
There are so many questions to be answered and there is nobody to answer them (at least definitavely). Maybe these things have changed since I last looked into it, but i doubt it.
