From KING5:
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.
