Flying Car Could Transform Warfare.  The Defense Advanced Projects Agency (DARPA) has cleared the Transformer (TX) program for takeoff. If it flies, by 2015 U.S. soldiers will be able to ride into battle aboard a four-person flying car that can cruise in the air like an airplane, drive on the ground like an SUV, rove 250 miles on one tank of fuel and not require a runway to get airborne.
