A Boeing 777 has crashed while landing at San Francisco International Airport.
All 290 passengers managed to escape escaped from the plane.
It is understood the tail snapped from the plane which was coming from Seoul, South Korea.
Passenger David Eun tweeted: "I just crash landed at SFO. Tail ripped off. Most everyone seems fine. I'm ok. Surreal..."
He added: "Fire and rescue people all over the place. They're evacuating the injured. Haven't felt this way since 9/11."
The plane, operated by Asiana Airlines, was coming from Seoul, South Korea and apparently crashed sometime before touching down on Runway 28.
