(AP) - A federal safety official says the cockpit voice recorder from Asiana Airlines Flight 214 showed the jetliner tried to abort its landing and come around for another try 1.5 seconds before it crashed at San Francisco airport.
National Transportation Safety Board chief Deborah Hersman says at a news conference Sunday the recorder also showed there was a call to increase airspeed roughly two seconds before impact.
Before that, she says, there was no indication in the recordings that the aircraft was having any problems.
The jetliner carrying 307 people crashed Saturday, killing two passengers and injuring dozens of other people.
Meanwhile, the president of Asiana Airlines says it will take time to determine the cause of the crash-landing, but he offered an apology within hours.
During a televised news conference in Seoul, airline President Yoon Young-doo bowed and said: "I am bowing my head and extending my deep apology" to the passengers, their families and the South Korean people over the crash.
Four pilots were aboard the plane and they rotated on a two-person shift during the flight, according to The Ministry of Land, Infrastructure and Transport in South Korea. The two at the controls at the time of crash were Lee Jeong-min and Lee Gang-guk.
Yoon described the pilots as "skilled," and when asked about the possibility of engine or mechanical problems, said he didn't believe they could have been the cause.
