The crew of a private airline narrowly escaped an accident in Jumla this week when a bird hit the windscreen, shattering it and spattering the pilot in blood. Feathered creatures have long been a menace at Tribhuvan International Airport. But it appears that another kind of four-footed trouble is causing concern in airports in other parts of the country. In Tumlingtaar, Sankhuwasabha, in east Nepal, airport authorities and the local municipality have got together in a campaign against canines straying onto the runway. Officials say the stray dogs are dangerous to domestic flights to and from Kathmandu and Biratnagar. They don't want to take chances, so they have taken to poisoning them. More than fifty have been killed so far and animal lovers will agree-it isn't the most humane way of aviation management.
