PHOENIX - The Federal Aviation Administration says mechanical failure is the reason why a Southwest Airlines flight to Ontario, Calif., had to return to Phoenix Sky Harbor International Airport.
Passengers aboard Flight 1015 told Phoenix radio station KTAR-FM that a bird struck one of the plane's engines about 45 minutes into the flight Thursday morning.
But the FAA says it was a mechanical problem that took out the jet's right engine.
FAA officials say the jet landed safely and passengers were put on a new plane for the flight to southern California.
No injuries were reported.
