        US National Transportation Safety Board chairwoman Deborah Hersman gave an update on the Asiana plane crash probe on Wednesday.
        She revealed that after the crash landing, passengers were told to stay seated, and did not begin evacuating the aircraft until 90 seconds later, when a fire was spotted outside the plane.
        Deborah Hersman, Chairwoman, US Nat’l Transportation Safety Board, said, "We talked about that in order to get certified, an aircraft manufacturer has to show that a fully loaded aircraft can be evacuated, fully evacuated within 90 seconds. What we saw here was that the first doors and slides weren’t opened for about 90 seconds."
        Hersman also said that according to the flight data recorder, in the last two-and-a-half minutes of flight, the plane was in "multiple autopilot modes and multiple auto-throttle modes". She said investigators are still examining whether the plane was commanded by the pilots in its final minutes and if the automated controls were activated inadvertently.
        Meanwhile, the Transportation Safety Board has corrected its previous statement, saying the plane’s crash point was in fact its wing, not its tail. This means the plane may have crashed at a lower height and a lower speed. The South Korean airliner crash-landed at San Francisco international airport on Saturday, killing two Chinese passengers and injuring many others.
