(SAN FRANCISCO) - 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.

Heavy smoke was seen billowing from the Boeing 777 in an amateur video posted on YouTube. Inflatable emergency slides have been deployed, but it's not clear if all passengers managed to get out. There was no immediate word on any casualties or injuries.
