A tragic crash at Jalalabad Airport in Afghanistan killed six American servicemen when a C-130 failed to lift off the runway. Media outlets are reporting between 10 and 12 total fatalities.

The American servicemen who perished in the crash were the aircraft’s crew. Military officials said the other casualties included five civilian contractors on board the C-130 and two Afghan civilians on the ground.

U.S. Air Force Maj. Tony Wickman told the Associate Press that the military did not believe the aircraft from shot down or tampered with by the enemy.

The six U.S. service members who died comprised the plane’s crew. The passengers were civilian contractors working with NATO’s Resolute Support mission and were the only passengers on board, Wickman added.

The airmen were assigned to the 774th Expeditionary Air Lift Squadron, part of the 455th, and the plane, a Super Hercules, crashed “shortly after take-off wholly within the airfield,” he said.

The Taliban claimed they shot the plane out of the sky, but the group is prone to exaggeration.

Wickman dismissed the claim, saying that “it is with high confidence that we can say it does not appear that enemy fire was involved.” Few other details were available and an investigation was underway, he added.
