KATHMANDU: Forty-nine people were killed when a Bangladeshi plane crashed and burst into flames near Katmandu airport on Monday, in the worst aviation disaster to hit Nepal in nearly three decades. Officials said there were 71 people on board the US-Bangla Airlines plane from Dhaka when it crashed just east of the runway and skidded into a nearby football field. Rescuers had to cut apart the mangled and burned wreckage of the upturned aircraft to pull people out, some of whom were buried under the scattered debris. “Forty people died at the spot and nine died at two hospitals in Katmandu,” police spokesman Manoj Neupane told AFP, adding another 22 were being treated in hospital, some in a critical condition. The cause of the crash was not immediately clear, but a statement from airport authorities said the plane was “out of control” as it came in to land. An airport source, who spoke on condition of anonymity, said there may have been confusion between air traffic control and the pilot over which runway the plane was meant to land on. Eyewitnesses said the plane crashed as it made a second approach toward the airport, bursting into flames after coming to a halt in a football pitch next to the runway. “It should have come straight but it went in the other direction,” said airport cleaner Sushil Chaudhary, who saw the crash. “I was worried it would hit another aircraft, but the pilot pulled the plane up. But then it crashed toward the field.”
