The Most Dangerous (And Expensive) Airports Ever Built

20. Paro International Airport – Bhutan

Year of construction: 1968
Risk factors: Closeness to the mountain, weather conditions

Paro International Airport is so dangerous that there are fewer than 24 pilots who are trained and authorized to use it. This airport only operates from sunrise to sunset, and its main danger is that it is surrounded by the Himalayan Mountains.

In addition, due to the weather conditions of the area, the runway (which is very short, by the way), is only visible to the pilots moments before they land on the ground. Before landing, pilots also have to watch out for the utility poles and houses that surround the landing zone.
