Qamdo Bamda Airport, Tibet
This airport is the highest airport in the world, located at 14,000 feet above sea level. It also has a very short runway of just 3.5 miles. Imagine if the pilot commits error while landing, it will surely be fatal. In a normal airport, the runway required should be long enough to bring the plane to a complete stop. For a runway located in a higher altitude, the length should even be greater. In this case though, it is not. Hence, it is always a dangerous airport to land in.
