American Airlines Grounds Dozens Of Planes Over Loose Seats
Description:American Airlines says it will ground dozens of Boeing 757s to make further fixes after seats became loose mid-flight on several planes.
American originally said the problem was due to a clamp that holds rows of seats to tracks on the aircraft floor.
But on Thursday, the airline said that a combination of wear, poor design and even soda spilled into the tracks caused pins to pop out of the grooves.(1:19)
