Rescuers in Nepal's mountainous west searched on foot for a missing Nepal Airlines plane carrying 18 people, as officials called off a chopper hunt for the aircraft, citing poor visibility. The plane with 15 passengers and three crew on board lost contact with air traffic controllers shortly after taking off from the popular tourist town of Pokhara, airline officials and police said.
