The Most Dangerous (And Expensive) Airports Ever Built

13. Cristiano Ronaldo Airport – Madeira, Portugal

Year of construction: 1973
Risk factors: Track built on the sea

Some describe Cristiano Ronaldo Airport as an engineering marvel. For others, it is a danger. The island of Madeira is so small that the runway of his airport had to be expanded over the sea. For this expansion, 180 pillars were built that hold the track over the water.

The strong winds on the island, as well as the narrow airstrip, make the maneuvers that the pilots carry out very complex. In fact, all those in charge of taking off or landing a plane on the island of Madeira must receive special training.
