OSAKA -- A man jumped into the engine of an Air China passenger plane just before its departure from Kansai airport at around 2 p.m. Thursday, according to airport police.

The man, believed to be a Chinese aircraft mechanic, was killed instantly, the police said.

The Boeing 767's departure was aborted as the incident left the engine inoperative, stranding some 200 passengers, they said.

Witnesses said the man suddenly ran out and jumped into the left engine as the aircraft made its way to the taxiway.
