A plane crash at Nepal's main airport killed 49 of the 71 people on board, police said yesterday as an investigation was ordered into the cause of the accident.
It appeared there was confusion over landing instructions before the plane, flying low and erratically, struck the ground and erupted in flames.
In a recording posted by air traffic monitoring website liveatc.net, the pilot asked for permission to land from the north, which an air traffic controller granted.
Less than a minute later the pilot said he was ready to land from the south, and the controller repeated that, clearing the plane to land from the south.
A separate conversation between the tower and a Nepali pilot added to the sense of miscommunication between the controllers and the pilot of the Bangladeshi plane before the crash.
