Air Bagan says it has found the black box after a dramatic Christmas Day crash-landing, as survivors told terrifying tales of escape and expressed disbelief that only two people died.

Details of the accident remain unclear, though the airline and officials have blamed heavy fog for the aircraft's crash into a rice paddy field where it burst into flames. Four foreigners were among 11 people injured.

Australian survivor, Anna Bartsch, on Wednesday described the landing as a fast, very bumpy roller-coaster ride. She recounted looking out the window, seeing flames and racing out to safety.

"It's amazing that the injuries were not more serious," said the 31-year-old. "It could have been much worse."

Air Bagan is sending the black box to Singapore to study the cause of the accident.
