OK, so it wasn’t an accident; it’s just that the NASA folks are getting rather good at intentionally crashing helicopters. The latest in its series of engineered rotorcraft crashes was conducted earlier this month when the agency dropped the more than four-and-a-half-ton fuselage of a former U.S. Navy CH-46 Sea Knight helicopter for the second time in little more than a year. Over the past five years the agency has conducted the crashes in partnership with the FAA, the U.S. Navy and U.S. Army at NASA Langley’s Landing and Impact Research facility, a 240-foot-high, 400-foot-long gantry, which was originally used by the Apollo Astronauts to practice moon landings.

In the most recent test another surplus sacrificial CH-46 was once again painted to resemble something hoping to hide itself on the African savannahs. Its striking polka-dot-on-white scheme enabled high-speed cameras, which followed the plunge at 500 images per second, to precisely chronicle the impact distortion through the process of full-field photogrammetry. When the aircraft was released from its cables, gravity did its thing, slamming the fuselage down through the arc of a pendulum at a speed of 30 mph, “a severe but survivable crash, according to civilian and military standards.”
