Passengers traveling Asiana Airlines plane crashed in San Francisco was originally told not to evacuate the aircraft skidded off the runway and stopped on the rear, federal safety officials said on Wednesday.
But a flight attendant saw fire, aircraft, and call out, 90 seconds after the crash, the National Transportation Safety Board Chairman Deborah Hochman in San Francisco, told a news conference. The first emergency response vehicle arrived after 30 seconds.
Boeing 777 crashed on Saturday killing two people were killed and over 180 injured.
Hochman said that in her fourth accident media conference, three flight attendants and his seat, ejected from the plane hit the runway in front, and lost part of its tail seawall. Two flight attendants temporarily pinned in the cabin, when two different aircraft evacuation chute deployment.
Xihesiman noted that immediate evacuation is not always the standard procedure or the pilot to make the right decision. "The pilot said that they are working with aircraft control," she said. "We do not know the pilots what they thought, but I can tell you that in a previous incident personnel do not have to evacuate. They wait for the other crew members," she said.
Safety requirements of the rules, be possible within 90 seconds of time to evacuate all passengers from the aircraft.
According to an interview with the 12 flight attendants machine six, was at first on the plane did not fire, Hochman said. But for fire evacuation began erupting inside, beaten and even fire extinguishers stewardess emergency personnel arriving.
Six flight attendants are still hospitalized, has not been interviewed. Asiana Airlines in a separate news conference outlined six other flight attendants. Attendants are being hailed as heroes who pushed evacuation and help passengers out smoking plane.
Hochman also said that a pilot was blinded by the flash of light, 500 feet above the ground when the aircraft is closed because it is close to the airport. She did not provide a theoretical what could cause such a flash.
Hochman said the plane's autopilot system and automatic throttle control is necessary to understand the last moments of pilots in flight to do further analysis.
Pilots told the NTSB is responsible for a plane, he relies on the plane throttle control to maintain its proper speed, and did not realize that this aircraft has been significantly slowed down as it approaches the runway, Hochman said on Tuesday. Slow is a key cause of the crash.
Hochman Again, even if the electronic control system failure, the pilot should still have been able to land the plane safely.
"There are two pilots in the cockpit of a reason," she said, they are responsible for monitoring all aspects of the flight, including key variables such as air velocity.
The role aircraft increasingly complex electronic control systems - and whether they can breed complacency among pilots - has been the subject of intense debate aviation, the problem is Asiana crash, it is possible to obtain a new urgency.
