The investigation into the crash of Asiana Airlines Flight 214 continues with emerging details today, but it's likely to be many months before it becomes clear what caused the Boeing 777 to land in the runway.
The plane slammed into a runway at San Francisco International Airport, killing two and injuring dozens.
As Miguel Marquez reports, we now have a better sense of what happened seconds before the crash.
“At about 35 seconds out and 500 feet up the pilot told investigators he saw a bright light and in response looked at the controls in the cockpit, including the speed indicator,” Marquez reports.
According to the head of the NTSB, “At about 500 feet the airspeed was approximately 134 knots.”
“The 350 ton plane was already below the 137 knot speed to which the pilot believed he had set the auto throttle,” Marquez explains.
“And for the first time we are hearing that at nine seconds before impact, 100 feet above the ground one of the pilots expresses concern about the aircraft's speed.”
The NTSB says they are trying to determine who said that, a part of its commitment to put everything it can into finding out what caused this crash.
