4 Gustaf III Airport (St. Bart)
Gustaf III Airport also known as Saint Barthélemy Airport is a public use airport located in the village of St. Jean on the Caribbean island of Saint Barthélemy. Both the airport and the island's main town of Gustavia are named for King Gustav III of Sweden, under whom Sweden obtained the island from France in 1785 (it was sold back to France in 1878). The airport is served by small regional commercial aircraft and charters. Most visiting aircraft carry fewer than twenty passengers, such as the Twin Otter, a common sight around Saint Barth and throughout the northern West Indies. The short airstrip is at the base of a gentle slope ending directly on the beach. The arrival descent is extremely steep over the hilltop traffic circle and departing planes fly right over the heads of sunbathers (although small signs advise sunbathers not to lie directly at the end of the runway).
5 Barra International Airport (Barra)
Barra Airport is the only airport in the world where planes land on the beach. BRR is situated in on the wide beach of Traigh Mhor, on Barra island, in the Outer Hebrides, Scotland. If you want to fly here commercially you will want to book with British Airways, which flies to Barra from Glasgow and Benbecula.
The airport is literally washed away by the tide once a day, and if you arrive on a late afternoon flight, you may notice a couple of cars in the parking lot with their lights on, which provides pilots some added visibility, since the airport is naturally lit. Needless to say you probably don't want to hang out at Barra Airport beach, unless you are a aviation junkie, in which case Barra Airport has a fool proof system, as sign that reads: "Keep off the beach. When the windsock is flying and the airport is active."
6 Madeira Airport (Madeira)
Madeira Airport also known as Funchal Airport and Santa Catarina Airport, is an international airport located near Funchal, Madeira. The airport controls national and international air traffic of the island of Madeira.
The airport was once infamous for its short runway which, surrounded by high mountains and the ocean, made it a tricky landing for even the most experienced of pilots. The original runway was only 1,400 metres in length, but was extended by 400 metres after the TAP Air Portugal Flight 425 incident of 1977 and subsequently rebuilt in 2003, almost doubling the size of the runway, building it out over the ocean. Instead of using landfill, the extension was built on a series of 180 columns, each being about 70m tall.
For the enlargement of the new runway the Funchal Airport has won the Outstanding Structures Award, given by International Association for Bridge and Structural Engineering (IABSE). The Outstanding Structures Award is considered to be the "Oscar" for engineering structures in Portugal.
