A video has surfaced showing the tragic crash of the Boeing 777 Asiana Airlines flight at San Francisco International Airport on Saturday.

The amateur video obtained by CNN shows the plane crashing and spinning counterclockwise and coming to a stop. The video was apparently shot about a mile from the crash scene.

The flight, with 307 people on board, originated in Shanghai and stopped in Seoul before heading for San Francisco. It was preparing to land in San Francisco when the rear of the plane struck the edge of the runway, severing the tail and causing the plane to erupt in smoke and flames. The crash killed two 16-year-old girls from China and sent 182 people to the hospital.

The National Transportation Safety Board is looking into reports that one of the girls may have been run over by an emergency vehicle.

"We are aware of the reports but don't have any details yet," NTSB spokeswoman Kelly Nantel told reporters. "Our investigators will be looking very closely at this issue.”

Additional details related to the crash indicate that the pilot who was landing Asiana Airlines Flight 214 was making his first landing with a Boeing 777 at the San Francisco airport. But it wasn't his first time flying to San Francisco nor his first time in control of a 777.

Lee Kang-kuk, the pilot who was in the captain's seat, had flown from Seoul to San Francisco several times between 1999 and 2004, the airline said.

As for the cause of the crash, the National Transportation Safety Board said Sunday that the cockpit voice and flight data recorders showed the flight was coming in too slow and too low and that the pilots apparently sped up seven seconds before impact.

Four seconds before impact, a stall warning sounded, warning the pilots the plane was about to lose its ability to stay in the air.

The voice recorder apparently showed the pilots tried to abort the landing less than two seconds before the plane crashed, NTSB head Deborah Hersman said.

The crew then made an internal decision "to initiate a go-around 1.5 seconds to impact," she said.

When asked if pilot error was to blame, Hersman said the crash landing was still under investigation.
