National Airlines Flight 102 was a cargo flight operated by National Airlines between Camp Bastion in Afghanistan and Al Maktoum Airport in Dubai, with a refueling stop at Bagram Airfield, Afghanistan. On 29 April 2013, the Boeing 747-400 operating the flight crashed moments after taking off from Bagram, killing all seven people on board.

The subsequent investigation concluded that improperly secured cargo broke free during the take-off and rolled to the back of the cargo hold, crashing through the rear pressure bulkhead and disabling the rear flight control systems. This rendered the aircraft uncontrollable, making recovery from a stall brought on by a change of balance from the shifted cargo impossible.
