They must be inserious financial trouble if they're selling their prototype. :( I have a picture of that one at the museum of science and industry in Chicago...
... And I quote: "We believe the Moller M400 Skycar prototype is a Category VIII (f) Aircraft as described by Part 121 of the United States Munitions List, of the International Traffic in Arms Regulations (ITAR), Federal Regulations (CFR) Part 120, July 1993. "
Jeez, is this some sort of weapon of mass destruction?
However, I think it's sad that prototypes like this are sold over the net... it's so degrading for the model...
