advertisement An associate professor at the University of Miami Miller School of Medicine was one of 19 people killed when a plane carrying tourists to Mount Everest crashed Sunday. Jagajan Karmacharya, 45, who was also the chief of vascular surgery at Miami’s Veterans’ Administration Hospital, was on a sightseeing flight with his fiancee and fellow VA hospital employee, Natalie Neilan, and his brother and his wife when the Buddha Air Beech aircraft crashed while returning to Kathmandu, according to the Miami Herald. Bad weather and foggy conditions may have led to the crash. Karmacharya, a native of Nepal, had taken the trip to introduce Neilan to his ailing mother. "J.J. was a wonderful surgeon, educator and individual," Alan Livingstone, chairman of the UM’s Miller School of Medicine told the Herald. "This is a great loss for us." Karmacharya had been on UM’s staff for three years. He left behind a teenage son.
