Three Humvees were caught on video (below) free falling after being dropped out of U.S. Army planes during airborne exercises in Berlin, Germany, on April 11.
The video was posted on the U.S Army W.T.F! moments Facebook page on April 19 and quickly went viral.
The Humvees are seen in the video breaking loose from their parachutes, going into free fall and smashing on the ground. During the failed heavy drop, the Humvees were destroyed on impact.
The Humvees were dropped by planes from the 173rd Airborne Brigade, notes The Associated Press.
An unidentified male filming the accident is heard on the video yelling profanities and laughing hysterically. Another voice notes that one of the vehicles is on fire and wonders aloud if it should be called in.
"The specific malfunctions that occurred on this day are under investigation," Army spokesman Maj. Juan Martinez wrote in an email to the Army Times. "There were multiple rehearsals and inspections of the equipment prior to mission execution. We cannot speculate on what went wrong until the investigation is complete."
Martinez added that the "investigation will receive the highest priority."
"While (the commanders of the 173rd) are aware of the video, it does not overshadow the hard work of the paratroopers, allies, and partners that took place during Saber Junction 16," Martinez insisted.
The Army doesn't know who filmed the costly and embarrassing accident, but Martinez said: "(Joint Multinational Training Command) is conducting (an investigation) to identify the person who shot the video. As far as disciplinary actions are concerned, nothing has been decided."
The military exercise is scheduled from March 31 to April 24 and includes thousands of soldiers from 16 European nations. The official goal is to test the 173rd division's ability to carry out land missions.
The incident was thoroughly mocked on Facebook by commenters who sounded as if they were in the military or had been in the service.
