As the investigation into the crash of Asiana Airlines Flight 214 continues, the NTSB revealed that an in-depth review of the on board voice and data recorder reveals the two pilots called to abort the landing, and that there were no problems until 50 seconds before impact.
CNN's Miguel Marquez reports that around 50 seconds out, the first officer sitting in the jump seat commented about the "sink rate," the speed at which the plane descends.
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.
"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. And for the first time we are hearing that at 9 seconds before impact, 100 feet above the ground one of the pilots expresses concern about the aircraft's speed," Marquez reports.
The NTSB says they are now trying to determine who said that.
