The pilots discussed several ways to land before the Air accident of Jeju Mortel

The Jeju Air Flight 2216 pilots reported three different plans to get the plane struck in a few minutes that crashed and killed 179 people in December, according to a partial transcription of their communication with the air controllers obtained by the New York Times.

The transcription shows that the pilots reported a strike of birds and have struck off a broadcasting call when they approached Muan International Airport in South Korea on the morning of December 29. They said they would turn left, then asked to turn right, with the intention of approaching the only track of the airport from the south. When this failed, the air controllers asked if they wanted to land in the opposite direction, and the pilots said yes.

The plane landed on its belly, invading the track and struck a concrete structure which housed aid to navigation, overflowing in a ball of fatal fire. Only two people – on -board agents at the rear of the plane, a Boeing 737-800 – survived.

The cause of the disaster, the most deadly plane crushing on the South Korean soil, is still under study, and the exchange between the pilots and the control tower could be a crucial piece of the puzzle. Indeed, it covers a period of about four minutes in which the two flight recorders of the plane, known as Black Boxes, had ceased to record.

Transcription does not include any information on the condition of the two jet engines or its power supply, which are intense areas of interest for investigators. It is still not known why the black boxes became dark or why the aircraft of the plane was not engaged.

The transcription was read on Saturday to relatives of the victims by a representative of a board of directors who was created to investigate the accident. The manager told them that reading had excluded parts of the conversation to protect the privacy of his participants, according to people who shared him with Times. The officials did not publicly publish the transcription and the council immediately responded to a request for comments.
