The Most Dangerous (And Expensive) Airports Ever Built

21. Tenzing-Hillary Airport – Nepal

Year of construction: 1964
Risk factors: Altitude

This small airport is popular because it is located at the same place where the vast majority of people begin their ascent to Everest Base Camp. Very often, fog, winds, and poor visibility end up delaying flights or even causing the airport to close for the day.

One of the main risks posed by this airport is that it is surrounded by mountains, and the altitude at which the airport is located is so high that aircraft engines sometimes have difficulty obtaining the oxygen they need during take-off acceleration.
