WORLD'S MOST DANGEROUS AIRPORTS

 Princess Juliana International Airport (Saint Martin)

Princess Juliana International Airport serves Saint Maarten, the Dutch part of the island of Saint Martin. It is the second busiest airport in the Eastern Caribbean. The airport is famous for its short landing strip ??” only 2,180 metres/7,152 ft, which is barely enough for heavy jets. Because of this, the planes approach the island flying extremely low, right over Maho Beach. Countless photos of large jets flying at 10--20 m/30-60 ft over relaxing tourists at the beach have been dismissed as fakes many times, but are nevertheless real. For this reason as well it has become a favourite for planespotters. Despite the difficulties in approach, there has been no records of major aviation incidents at the airport.

 Juancho E. Yrausquin Airport (Saba, Netherlands Antilles)

Juancho E. Yrausquin Airport is the only airport on the Caribbean island of Saba, in the Netherlands Antilles. It is well known among experienced fliers for the way in which airplanes must approach or take off from the airport.

Yrausquin Airport covers a relatively large portion of the small island of Saba. Some aviation experts are of the general opinion that the airport is one of the most dangerous in the world, despite the fact that no major tragedies have happened at the facility. The airport's sole runway is marked with an X at each end, to indicate to commercial pilots that the airport is closed for commercial aviation.

The danger arises from the airport's physical position. It is flanked on one side by high hills, and on the other side and at both ends of the runway by cliffs dropping into the sea. This creates the possibility that an airplane might overshoot the runway during landing or takeoff and end up in the sea or on the cliffs.

  Courchevel (France)

Courchevel is the name of a ski area located in the French Alps, the largest linked ski area in the world. It's airport has a certain degree of infamy in the aviation industry as home to a relatively short runway, with a length of 525 m (1,722 ft) and a gradient of 18.5%. It's so short that you have to land on an inclined strip to slow down and take off on a decline to pick up enough speed.

"You take off downhill and you land going uphill," Schreckengast says. He adds that the hill, which has an 18.5 percent grade, is so steep that small planes could probably gain enough momentum rolling down it with no engines to safely glide off the edge. Landing at Courchevel is obviously no easy task, so pilots are required to obtain certification before attempting to conquer the dangerous runway.


Congonhas Airport ( Sao Paulo, Brazil)

Most major cities have an airport, but rarely are they built just 5 miles from the city center, especially in metropolises like Sao Paulo. Congonhas' close proximity to downtown can be attributed in part to the fact that it was completed in 1936, with the city experiencing rapid development in the following decades.

While having an airport only 5 miles from the city center may be a convenience for commuters, it places a strain on both pilots and air traffic control crews. "It becomes a challenge in terms of safety to just get the plane in there," Schreckengast says. "Then you throw on noise restrictions and these terribly awkward arrival and departure routes that are needed to minimize your noise-print and it becomes quite challenging for pilots." Fortunately, Sao Paulo's many high-rise buildings are far enough away from the airport that they aren't an immediate obstacle for pilots landing or taking off.

Kansai International Airport(Osaka, Japan)

Land is a scarce resource in Japan, so engineers headed roughly 3 miles offshore into Osaka Bay to build this colossal structure. Work on the manmade island started in 1987, and by 1994 jumbo jets were touching down. Travelers can get from the airport to the main island of Honshu via car, railroad or even a high-speed ferry.

Kansai's artificial island is 2.5 miles long and 1.6 miles wide—so large that it's visible from space. Earthquakes, dangerous cyclones, an unstable seabed, and sabotage attempts from protestors are just some of the variables engineers were forced to account for. As impressive as the airport is, Stewart Schreckengast, a professor of aviation technology at Purdue University and a former aviation consultant with MITRE, cautions that climate change and rising sea levels pose a very real threat to the airport's existence. "When this was built, [engineers] probably didn't account for global warming," he says. "In 50 years or so, this might be underwater."

Madeira Airport (Madeira Portugal)

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.

Ice Runway (Antarctica)

 

The Ice Runway is one of three major airstrips used to haul supplies and researchers to Antarctica's McMurdo Station. As its name implies, there are no paved runways here—just long stretches of ice and snow that are meticulously groomed.

There is no shortage of space on the Ice Runway, so super-size aircraft like the C-130 Hercules and the C-17 Globemaster III can land with relative ease. The real challenge is making sure that the weight of the aircraft and cargo doesn't bust the ice or get the plane stuck in soft snow. As the ice of the runway begins to break up, planes are redirected to Pegasus Field or Williams Field, the two other airstrips servicing the continent.

Svalbard Airport(Norway)

 

Svalbard is a cluster of Norwegian islands sitting in the Arctic Ocean. While there are three airports within the archipelago, two of which are used mainly to transport miners, Svalbard Airport is open to commercial travel, making it the world's northernmost airport that tourists can book tickets to.

Engineers used the region's brutally cold climate to their favor during construction and built the runway on a layer of permafrost. The airport was completed in 1975, but slight seasonal changes caused sections of the runway to become uneven, forcing the need to repave the runway on several occasions. A project was launched in 1989 aimed at insulating troublesome sections of the runway from the ground, which proved relatively successful. However, a 2002 study indicates that rising temperatures in the area may increase the need and frequency of maintenance efforts and repaving.
