Vedpal Singh, who was sitting in the middle of the aircraft and survived the crash with his family, said there was no forewarning from the pilot or any crew members before the plane touched down hard and he heard a loud sound."We knew something was horrible wrong," said Singh, who suffered a fractured collarbone and had his arm was in a sling. "It's miraculous we survived," he said. A visibly shaken Singh said the plane went silent before people tried to get out anyway they could. His 15-year-old son said luggage tumbled from the overhead bins The entire incident lasted about 10 seconds. Another passenger, Benjamin Levy, 39, said it looked to him that the plane was flying too low and too close to the bay as it approached the runway. Levy, who was sitting in an emergency exit row, said he felt the pilot try to lift the jet up before it crashed, and thinks the maneuver might have saved some lives. "Everybody was screaming. I was trying to usher them out," he recalled of the first seconds after the landing. "I said, 'Stay calm, stop screaming, help each other out, don't push.'" Hayes-White said she did not know the ages or genders of the people who died, but said they were found on "the exterior" of the plane. She said the 307 passengers and crew members had been aboard had been accounted for following several hours of confusion during which authorities said they were unsure of the whereabouts of more than 60 people who, as it turned out, had been evacuated to a different area of the airport. Based on witness accounts in the news and video of the wreckage, Mike Barr, a former military pilot and accident investigator who teaches aviation safety at the University of Southern California, said it appeared the plane approached the runway too low and something may have caught the runway lip â¿¿ the seawall at the end of the runway.
