A National Airlines B747-400 cargo plane crashed on takeoff Monday at Bagram Airbase in Afghanistan, killing all seven crewmembers.
"Safety is always our top priority," National Airlines President Glen Joerger said in a written statement. "This is a devastating loss for our family and we'll work diligently with authorities to find the cause. Most importantly, our thoughts and prayers are with our crewmembers and their families."
The Taliban have claimed responsibility for downing the plane, but NATO dismissed the claim, The Guardian reports.
The plane was carrying vehicles and general cargo.
