Asiana Airlines Boeing 777 Crashes During Landing At San Francisco International Airport

July 6, 2103 - Full Report - A Boeing 777 en route from Seoul, South Korea crashed upon landing at San Francisco International Airport Saturday afternoon, flipping over after its tail fell off. No casualties are reported at this time. The cause of the crash is also unknown, though one official, who asked not to be named, said the plane was not making an emergency landing.

Witnesses say the landing gear had come down when the tail came off, causing the plane to flip upside down and eventually skid to a stop on its back. (UPDATE 3:41 p.m.: Reports are now indicating that the plane is rightside up.) Smoke was seen billowing from the massive jet, and after rescue crews put out the fire much of the plane's roof appeared to have burned off.

The 777 is a large model airplane that can carry up to 450 people.

David Eun, a self-described "digital media guy," tweeted from inside the plane, claiming that he had crashlanded in San Francisco but was okay:
