Asiana Airlines Flight 214 'black boxes' detail San Francisco crash landing
The crew of the Asiana Airlines aircraft that crashed Saturday at San Francisco airport tried to increase its speed and abort its landing just seconds before it hit the seawall in front of the runway, according to flight recorders recovered by the National Transportation Safety Board.

Among other things, investigators want to interview the four pilots onboard and the cabin crew as well as passengers. Regarding the flight crew, investigators will be looking at how well they worked together and followed established procedures as well as such issues as cockpit configuration and issues that could affect crew performance, especially on a flight lasting more than 10 hours – fatigue, use of medications, sleep disorders, or drug and alcohol use.Skip to next paragraph

Visibility was 10 miles at the time, and there was a slight wind (7 knots) from the left. No wind shears or other potentially adverse conditions had been reported.
It was noted that aircraft landing on Runway 28 Left were operating VFR (using Visual Flight Rules), which means that the electronic glide path was not in service and it was up to the pilot to fly the approach to landing visually and manually.
In this case, the Federal Aviation Administration (FAA) had issued a worldwide “notice to airmen” (NOTAM) that the glide path on that runway would not be operating from June 1 to August 22 while construction to improve the runway was underway.
As Hersman and airline pilots point out, this was not an unusual circumstance.
The NTSB has asked anyone with still photos or video of the crash to contact the agency through its web site.
Most such investigations take 12-18 months to complete, but Hersman pointed out that the NTSB can issue safety recommendations based on an ongoing investigation at any time.
There were 307 people aboard Flight 214, 291 passengers and 16 crew members. The flight had originated in Shanghai and stopped in Seoul before flying on to San Francisco.
Two people aboard the plane died (both Chinese teen-age girls). Of the 182 injured people taken to hospitals, at least 49 were in critical condition late Saturday. The remaining 133 had minor to moderate injuries, while many of the other passengers or crew members had more minor injuries that didn't require extra treatment, according to the Associated Press. Thirty of the passengers were children.
"I think when we look at this accident we're very thankful that we didn't have more fatalities and serious injuries and we have so many survivors," NTSB Chairman Hersman said on CNN's "State of the Union" Sunday. "Really, very very good news as far as survivable accidents, which many accidents are."
The robustness of the 777 aircraft allowed many passengers to walk away from a catastrophic crash landing, other experts point out – including such safety features as multiple redundant systems, stronger seats, and the use of nontoxic materials in construction. Also, the Federal Aviation Administration now requires new aircraft models to be equipped and staffed to allow all passengers to exit within 90 seconds.
South Korean officials said the plane's passengers included 141 Chinese, 77 South Koreans, 61 Americans, three Canadians, three from India, one Japanese, one Vietnamese, and one from France, while the nationalities of the remaining three haven't been confirmed.
