PHOENIX (AP) — A United Express flight from San Francisco to San Antonio was diverted to Phoenix on Thursday because of a threat that authorities said came from aboard the plane.
Officials at Phoenix Sky Harbor International Airport said Flight 5573 landed at 4:45 p.m. Thursday and everyone on board was evacuated.
Officials with SkyWest Airlines Inc., which operates flights under the United Express brand, said there were 42 passengers, two pilots and two flight attendants on the flight. A SkyWest spokeswoman referred all questions about the threat to Phoenix authorities.
Phoenix police spokesman Sgt. Steve Martos said "the reported threat was on the plane" but he couldn't provide any details.
A bomb squad and police dogs were searching the plane and luggage "to make absolutely sure there's no threat," and the passengers and crew were being interviewed, Martos said.
Sky Harbor officials said passengers were bused to a waiting area in a terminal and United was making plans to get them on another flight to San Antonio.
The plane was isolated on the northwest side of airport and Sky Harbor officials said the incident wasn't causing any flight delays.
United Express is the brand name for several regional airlines that operate shorter flights for United Airlines.
