Texas airport worker killed in freak accident involving plane engine.

An airport worker in Texas died after being sucked into the engine of a Delta plane that was taxiing towards its gate with one engine turned on. The incident was unrelated to safety procedures, according to the worker's employers, but an investigation is ongoing. The National Transportation Safety Board is gathering information, and Delta Air Lines said it was "heartbroken" over the loss of an "aviation family member's life."
