Investigators are deep into the search for clues in the crash of a Boeing 777 at San Francisco's airport this weekend.
Two people were killed and more than 160 injured, with 49 of those still in serious condition.
Investigators say Asiana Flight 214 was coming in much too slowly for a landing Saturday. They say crew members cried out for increased speed, but it was too late. The plane stalled just as the pilots tried to abort the landing.
"A call to initiate a 'go around' occurred 1.5 seconds before impact," Deborah Hersman, head of the National Transportation Safety Board, said.
According to newly released information, the pilot in the deadly crash was in training and had only logged 43 hours flying a Boeing 777.
An Asiana spokeswoman said the pilot was flying with a very experienced co-pilot and had thousands of hours of experience flying other aircraft.
Meanwhile, doctors at San Francisco General Hospital continue to work around the clock to save the injured.
"The most critically injured people came right away," Rachael Kagan, spokeswoman for the San Francisco General Hospital & Trauma Center, said. "Some of them had burns, they had fractures, they had internal injuries, internal bleeding and also head injuries. We also saw spinal injuries."
Passengers sitting in the back of the plane sustained the worst injuries. Among them were 35 middle and high school students from China on their way to a Christian church and school in Southern California to learn English. The two fatalities were from that group.
"I knew that there was some connection to the airplane, but I didn't realize that two of the deaths had been from the children we were hosting," church member Bobbie Candler Buyalos said.
"I have three children and it struck me as a mom to think about sending my children off on what was supposed to be a pleasurable trip and to have something like that happen," she said.
The NTSB plans to speak with the pilots in the coming days in an investigation that could take months.
Officials are also looking into reports that one of the teenage victims may have been struck by a rescue vehicle on the runway.
