The 30-seat MI 17 helicopter of the Shree Air has been grounded in Lukla from Wednesday due to bad weather condition though the helicopter was supposed to bring the tourists to Kathmandu.

Tenzing Hillary Airport, the small airport which is located at an altitude of 2,860 meters is one of the busiest airports in Nepal as it is the entry point for the visiting Mount Everest (Mt. Qomolangma). In January 2008, the airport was renamed in honor of Sir Edmund Hillary and Sherpa Tenzing Norgay, the first persons to reach to the summit of Mt. Qomolangma. The surrounding terrain, thin air, highly changeable weather and the airport\'s short, sloping runway make it one of the most challenging landing strips in the world.
