Qamdo Bamda Airport, Tibet

Tibet is located in the world’s highest mountains, the Himalayas, so it shouldn’t surprise anyone that Qamdo Bamda Airport is one of the world’s highest, perched more than 14,000 feet above sea level. Another extraordinary and extreme feature of this airport is its 3.5-mile-long runway, which is considered to be the longest in the world.

The lower concentration of oxygen at such altitude may cause some discomfort to newcomers and it also lowers the aircraft engines’ performance, making landing there a nightmarish experience for everyone on the plane.
