“Europe's most dangerous airport” is in Madeira. The runway is so narrow that it was extended by 655 feet in 1977 after a crash killed 131 people, according to the Independent.  Pilots hate the airport for other reasons as well – it’s surrounded by rocky hills and an utter drop into the ocean. The location is not ideal either, as strong winds often cause severe turbulence.
