National Air Cargo Flight 102Monday April 29, 2013
The civilian cargo plane crashed and burned shortly after taking off from runway 03 at Bagram Air Base. The plane was carrying 5 armored vehicles. The airline's cargo operations manual did not explain how to account for the orientation of the tiedown straps when calculating how many were needed, and the inexperienced and uncertified loadmaster used too few straps. When the plane began climbing, the rearmost vehicle, weighing 28,000
pounds, broke free and smashed into the tail, severing two hydraulic systems and the elevator jackscrew, leaving the plane uncontrollable.
