NASA Crashes Plane to Test Emergency Beacons (Video)

NASA sent a small airplane plummeting to Earth today (Aug. 26), for safety's sake. Scientists and engineers at the space agency's Langley Research Center in Virginia dropped a Cessna 172 from a height of 100 feet (30 meters), in a crash test that was captured on video. Two dummies were aboard the 1974 airplane, which was outfitted with a number of cameras and sensors, as well as five emergency locator transmitters (ELTs).
