SEATTLE – A flight from Sea-Tac Airport to San Francisco had to turn around after a row of seats slid, crushing another row of passengers Sunday night.

United Airlines Flight 1139 took off at about 7 p.m.

A Sea-Tac Airport spokesman says while the plane was in the air, row number three slid back onto those passengers sitting in the next row.

However, a passenger on that flight tells KING 5 news the seats actually slid as the plane was just beginning to accelerate.

A passenger took this photo of what appears to be a mechanic securing the seats that slipped on United Flight 1139.

"The screaming was horrible," said the passenger, who added that four or five people got off the plane with police and paramedics after the flight returned to Sea-Tac. Airport officials say one passenger sitting in the fourth row was taken off the plane to Highline Community Hospital.

United says a bolt appeared to be loose, causing the seats to slide. The passenger says mechanics came on board to tighten the bolts and take photos of the seats.
