WASHINGTON, Aug. 11, 2011 (Reuters) — An unmanned experimental aircraft designed to glide down from the upper atmosphere at 20 times the speed of sound lost contact with ground control on its second test flight on Thursday, a Pentagon agency said.
The Falcon HTV-2 was launched from Vandenberg Air Force Base in California on a rocket and successfully separated from the launch vehicle, the Defense Advanced Research Projects Agency said.
