Three Humvees being dropped from airplanes and crashing to the ground

Under an U.S. Army airborne exercise in Germany (Hohenfels) a Humvee broke free of its rigging and plummeting to the ground, followed by another — and another. The scene starts serenely as equipment is dropped by parachute April 11 from planes with the 173rd Airborne Brigade flying across blue skies until the first Humvee breaks free and crashes to the ground. 
It’s followed by a second and then a third Humvee crashing to the ground and increasing laughter on the video. The Army says nobody was hurt, and it’s investigating what went wrong — and who shot the video.
