On December 31st, an American Airlines employee was tragically killed at an Alabama airport after being pulled into an engine. The NTSB's preliminary report revealed that the ground crew had held a safety briefing prior to the airplane arriving at the gate, and that the flight crew had elected to leave both engines running during the two-minute engine cool-down period. The NTSB is continuing to investigate the incident, and has not yet released a final report or the name of the employee.
