Asiana Airlines San Francisco crash: piecing together the evidence
Investigators have found the 'black boxes' from the Asiana Airlines crash landing in San Francisco. Weather was clear and there had been no reports of mechanical difficulties, which points to pilot performance.
Investigators looking for clues to the Asiana Airlines crash landing at the San Francisco Airport found their first major piece of evidence Sunday: the “black boxes” containing the flight data recorder and the cockpit voice recorder.Skip to next paragraph

The boxes – actually, they’re orange – are designed to tell experts exactly what was happening with the Boeing 777 airliner, including mechanical and electrical data, as well as what crew members said to each other as the aircraft approached Runway 28 Left.
What is obvious from photos and videos is that Flight 214 struck the sea wall at the end of the runway well short of the normal landing spot, which knocked off the tail section, one engine, and parts of the wings as the aircraft slammed down hard and slid to a stop to the left of and several hundred yards up the runway.
Eyewitnesses report seeing the aircraft in an unusually nose-high, tail-low attitude as it flew in low over the water, suggesting that the pilot flying the 777 – one of four flight crew members assigned to the 10-hour-plus flight from Seoul, South Korea – was trying to regain altitude.

The situation seemed to have surprised the flight crew. As they talked to flight controllers on the ground during the approach to San Francisco, they gave no indication of any difficulties nor did they alert passengers and cabin crew to the impending crash. Weather was not a factor. The approach and landing were being made visually and “hands-on,” which is not unusual.
"We just arrived on scene a few hours ago,” Ms. Hersman said on ABC's "This Week." “We have a lot of work ahead of us. We have teams that will be looking at aircraft operations, at human performance, survival factors, and we'll be looking at the aircraft. We'll be looking at power plants, systems, and structures. And so we really want to make sure we have a good understanding of the facts before we reach any conclusions."
Hersman said investigators expect to speak with the pilots “in coming days.”
At a news conference in Seoul, Asiana Airlines President Yoon Young-doo emphasized that the four South Korean pilots were highly experienced – three of them with more than 10,000 hours of flight time and the fourth with nearly that many.
But absent any indication of mechanical failure, the investigation will have to focus on pilot performance, including the possible role of fatigue after such a long overnight flight.
Reuters reports that an automated instrument landing system had been turned off at the San Francisco airport due to construction.
