LOS ANGELES >> An airline jet being towed on a taxiway collided with a shuttle bus at Los Angeles International Airport late Friday, injuring five people.

The Federal Aviation Administration said Saturday that it is investigating the incident involving an American Airlines Airbus A321 jet. There were no passengers on board.

The airport said on Twitter that the jet was being towed from a gate to a parking area when it “made contact” with a shuttle bus that was transporting passengers between terminals.

The Los Angeles Fire Department said four people were taken to hospitals after the “low-speed collision,” which occurred around 10 p.m. The driver of the tug pulling the plane was in moderate condition and the driver and two passengers on the bus were in fair condition, the department said.

The only person on the plane, a worker, was treated but declined to be taken to a hospital, according to the fire department.

There was no interruption to airport operations, the airport said.

A large skid mark from the jet’s tire was visible, and the windshield of the bus had extensive damage, according to ABC7.com.
