British investigators have arrived in Nepal to investigate the plane crash that killed 19 people including seven Britons heading to the Mount Everest region for a trekking holiday, officials said Sunday. Nepal's aviation ministry said two staff had come to Kathmandu to assist local authorities looking into the accident, which killed seven Britons, four Chinese, an American and seven local passengers and crew. "Two experts from UK have arrived in Kathmandu to assist in the investigation of the crash," Suresh Acharya, a senior official in the aviation ministry, told AFP. "They are here under the provision of the International Civil Aviation Convention which states that experts from the country whose citizens are dead in a crash can provide expert support for investigation process. "The British government expressed willingness to send them and we are ready to use their expertise." The twin-propeller Sita Air plane had just taken off on Friday from Kathmandu and was headed to the town of Lukla, the gateway to Mount Everest, when it plunged into the banks of a river near the city's airport around daybreak. The British investigators will assist a government commission due to report on the cause of the crash within three months. "They will visit the crash site, collect factual information and will work with the investigation commission. They will attend the first meeting of the probe committee scheduled for Sunday afternoon," Acharya said. The youngest British victim was Ben Ogden, a 27-year-old Oxford University graduate who recently qualified as a solicitor and was a rising star at a London law firm. Other victims include Timothy Oakes, a 57-year-old secondary school adviser, and his friend Stephen Holding, a 60-year-old retired science teacher. Building contractor Vincent Kelly, 50, and his brother, property developer Darren, 45, were also killed along with Chris Davey, 52, an electronics engineer, and Ray Eagle, 60, a marathon runner. The victims were too badly burned to be individually identified, hospital officials said, the foreigners' bodies will be handed to relatives only when the results of tests on DNA samples sent abroad have been received.
