The Most Dangerous (And Expensive) Airports Ever Built

36. El Hierro Airport – Tenerife, Spain

Year of construction: 1972
Risk factors: Air control system

In 2010, El Hierro earned the title of “the most dangerous airport in Spain,” thanks to its systems. An automatic air control system had just been implemented that year that had been rejected by other European countries. With this system, planes land and take off without the direct assistance of the control tower personnel.

The new system caused quite a stir, as weather conditions in the area make maneuvering difficult, and pilots need help from personnel in the control tower. The new circumstances put both pilots and passengers at risk.
