A plane crashed while landing at San Francisco International Airport Saturday morning after its tail came off while it was touching down on the runway.

According to a witness, around 11:20 a.m. the plane was just about to land -- its landing gear had come down -- when the tail of the plane came off.

After wobbling for a minute, the aircraft flipped upside down, coming to a stop on runway on it's back.

The plane, reportedly a Boeing 777, was coming from South Korea, according to flight tracking information.
