(San Francisco - Melanie Woodrow Reporting)
Federal investigators are trying to pinpoint what happened seconds before Asiana flight 214 went down Saturday morning.
At least 19 people are still in the hospital as of Monday morning and six are in critical condition.
Two teenagers were also killed.
Investigators from the National Transportation Safety Board say the plane was coming in too slow when its tail slammed into the rocky sea wall in front of the runway.
An analysis of the flight data recorders shows the pilots tried to speed up, but it was too late.
Deborah Hersman, Chairman of the NTSB said, "A call to initiate a go-around occurred 1.5 seconds before impact."
Investigators hope to interview the crew and victims over the next couple of days.
Korean officials say the pilot in control of the aircraft at the time of the crash is a veteran with nearly 10,000 hours of flight time, but he was new to the Boeing 777 and was landing the plane at San Francisco's International Airport for the first time.
16-year-old's Wang Linjia and Ye Mengyuan from a town near Shanghai, China died in the crash.
They were headed to a summer camp with their middle school classmates.
San Francisco Fire Chief, Joanne Hayes-White, says they are looking into the possibility that an emergency vehicle rushing to the scene may have hit one of the girls and killed her.
182 passengers were taken to the hospital, where doctors expected to see burn victims but that is not what they got. "What we did see was a huge amount of spine fractures. Some of them include paralysis," said Doctor Margaret Knudson with San Francisco General.
Most of the injured passengers were sitting in the back of the plane.
The investigation is ongoing.
