Airliner returns to L.A. after passenger incident
LOS ANGELES (AP) — A passenger allegedly uttered an anti-American threat during a confrontation with flight attendants Thursday, prompting an airliner to return to Los Angeles under escort by Air Force jet fighters.
The unidentified man and his travel companion on Air Canada Flight 792 to Toronto were handed over to the FBI, said Nicole Couture-Simard, spokeswoman for Air Canada in Montreal.
"Shortly after departure a male passenger was apprehended smoking in the lavatory," she said. "The passenger became verbally abusive and uttered an anti-American threat."
Couture-Simard would not describe the threat.
FBI spokeswoman Laura Bosley could not immediately give details on the passenger.
The Boeing 767 landed safely about half an hour after takeoff, authorities said.
Couture-Simard said it was not necessary to restrain the passenger: "The pilot elected to return to Los Angeles as a precautionary measure only."
There were 145 people on the plane, including a crew of seven, an airport spokeswoman said. The jet returned to the airport around 1:15 p.m. and passengers were booked on the next flight.
Two F-16s escorted the Air Canada flight into the airport, authorities said. Who contacted the jets was not immediately clear, but Air Force jets normally respond to civilian incidents only at the request of the Federal Aviation Administration, said Maj. Barry Venable, spokesman for the North American Aerospace Defense Command.
The incident occurred as Gov. Gray Davis was traveling to an airport press conference on a shuttle bus.
"We were about five minutes out of Lot C when those two jets buzzed the airport, so we knew something was up," said Davis, who announced a call-up of National Guard troops to bolster security, then took a flight to San Francisco to demonstrate confidence in air travel.
