No flights have taken off from Nepalgunj for the mountainous districts of Karnali for two days. A lack of en-route weather details has prevented the Civil Aviation Authority of Nepal (CAAN) from issuing permits to planes flying from Nepalgunj to high-altitude airports in Karnali. This has stopped all flights to Simkot, said Mohan Giri, chief of CAAN’s Simkot office.
