Flight 214 from Seoul had 307 passengers on board, including 16 crew members. The four South Korean pilots were all very experienced and “veteran pilots”, according to Asiana Airlines CEO and President Yoon Young-Doo, who also said that a mechanical error has "yet to be confirmed". He said the flight originated from Kansai International Airport in Osaka, Japan, stopped in Seoul and then carried on to San Francisco.
The passengers included 61 US citizens, 77 Korean nationals and 141 Chinese nationals. The two people killed were both 16 years old: Ye Mengyuan and Wang Linjia, students at Jiangshan Middle School in eastern China.
Eyewitnesses say the plane touched down several hundred feet before the beginning of the runway. They saw puffs of smoke when the main wheels or tail hit the ground, just before the plane erupted in flames. Passengers were seen jumping down emergency inflatable slides to the tarmac.
Some commercial pilots also saw the crash from nearby hotels or the airport. They concurred that the plane seemed to land unusually hard and short, then spun around the strip before they saw flames.

According to preliminary reports, the pilots were following a routine visual approach and didn't radio any problems or declare an emergency before impact. Investigators will likely be examining an instrument-landing system that wasn't operational at the time, and had been out of commission on that strip at the San Francisco airport for weeks due to runway improvement work.
Capt. Chesley Sullenberger, the pilot who landed the Hudson flight and now CBS News aviation and safety analyst, said it was possible that the ongoing construction at San Francisco International Airport would be examined as a factor in the Asiana crash.
