NASA sponsored competition seeks Jetson's like future

c|net's News.com is running an article about a NASA sponsored competition that seeks to find the most fuel efficient personal aircraft vehicle (PAV). The competition is being held at Charles Schultz Sonoma County Airport in California, conjuring up images in my head of Snoopy cruising around on his dog house, but I digress. "These air vehicles can travel in three dimensions without any traffic jams, and the computer technology today enables travel that can be on demand at speeds three to four times faster than cars with equivalent gas mileage." If these guys get their way, we might all be flying our cars to work someday in the not too distant future. Think "The Jetsons" or perhaps "Blade Runner".
