Pentagon releases results of 13,000 mph test flight over Pacific

The results are in from last summer’s attempt to test new technology that would provide the pentagon with a lightning-fast vehicle, capable of delivering a military strike anywhere in the world in less than an hour.
In August the Pentagon’s research arm, known as the Defense Advanced Research projects Agency, or DARPA, carried out a test flight of an experimental aircraft capable of traveling at 20 times the speed of sound.
The arrowhead-shaped unmanned aircraft, dubbed Falcon Hypersonic Technology Vehicle 2, blasted off from Vandenberg Air Force Base, northwest of Santa Barbara, into the upper reaches of the Earth’s atmosphere aboard an eight-story Minotaur IV rocket made by Orbital Sciences Corp.
After reaching an undisclosed altitude, the aircraft jettisoned from its protective cover atop the rocket, then nose-dived back toward Earth, leveled out and glided above the Pacific at 20 times the speed of sound, or Mach 20.
The plan was for the Falcon to speed westward for about 30 minutes before plunging into the ocean near Kwajalein Atoll, about 4,000 miles from Vandenberg.
But it was ended about nine minutes into flight for unknown reasons. The launch had received worldwide attention and much fanfare, but officials didn’t provide much information on why the launch failed.
