Cool Video: HTV-2 Re-enters Atmosphere at Mach 20

DARPA’s August 11, 2011, second flight of the HTV-2 hypersonic glider – which ended prematurely after only 9min of a planned 30min flight across the Pacific – was captured on handheld video camera by a crewmember of one of the ships tracking the vehicle’s telemetry as it re-entered the Earth’s atmosphere at 20 times the speed of sound. DARPA does not yet know while the flight ended prematurely. The first HTV-2 flight, on April 22, 2010, also ended after just 9 min.
