An animation released Sunday gives a better idea of what led to Saturday's crash in San Francisco of a plane reportedly carrying at least one New York City passenger that killed two people and injured nearly 200.
This animation shows the moments before the crash, with the tail of Asiana Airlines Flight 214 striking the seawall at the start of the runway.
The tail then disintegrated and the engine on the plane's left wing blew off as the fuselage skidded across the runway.
Some passengers have said the pilot increased engine power just before touchdown.
Chinese state media says the two people killed were both 16-year-old students.
Nearly 200 people were hurt, and several of them remained in critical condition on Sunday.
The National Transportation Safety Board is now investigating.
"We're going to have to corroborate a lot of information, the radar data, the [air traffic control] information, and the flight data recorder parameters and also interview the pilots," said NTSB Chairman Deborah Hersman. "It's really important to put all you have the pieces of the puzzle together, to not just understand what happened, but understand why it happened so we can prevent accidents like this occurring in the future."
More than 300 people were on the flight, and passengers were visibly shaken by their ordeal.
"It sounded like we were about to land. The nose of the plane, as you know, it goes up a little bit, and then full throttles start hitting hard. We felt like we were going up again," said one passenger.
"As it landed, it was a hard loud noise and then the masks fell down and then severe stuff started falling down on people and everyone started screaming," said another passenger.
Published reports said that at least one New Yorker, Samsung executive David Eun, was aboard the plane. Eun posted on his Twitter page, "I just crash landed at SFO. Tail ripped off. Most everyone seems fine. I'm ok. Surreal..."
Eun later posted that he was OK and was eventually allowed to leave San Francisco International Airport.
South Korean officials say four pilots were aboard the flight, rotating in two-person shifts.
