On July 12th, Nyingchi Airport, the third civil airport in Tibet performed its test operation. The airport with a total of 0.78 billion yuan invested aims to transport 1.2 million people every year.

Known as"the world's most difficult airport for planes to reach", Nyingchi Airport is situated in the valley of Yarlung Zangbo River in the Southeast of Qinghai-Tibet Plateau, surrounded by over 4000-meter high mountains enveloped by cloud and frogs throughout the year. Planes have to fly through the narrow and winding river valley. The narrowest flight path is less than 4 kilometers from one mountain ridge along the valley to the opposite one. According to meteorological data, there are just 100 days overall that are airworthy in the airport each year.
