What You'll Learn

Tenzing-Hillary Airport, Nepal
Tenzing-Hillary Airport, also known as Lukla Airport, is located 9,383 feet above sea level in the Himalayas, surrounded by steep, mountainous terrain. Its short runway, at 1,729 feet, is perched on a mountain shelf with a 2,000-foot drop on one side and a stone wall on the other. The high altitude and surrounding terrain present significant challenges for pilots, including reduced aircraft engine power and difficulties in slowing down and landing. The unpredictable weather in the region, with sudden snow, fog, and cloud cover, further adds to the risks.
Due to these factors, Tenzing-Hillary Airport has been referred to as the most dangerous airport in the world. The airport's single runway, with challenging terrain at both ends, makes it difficult for aircraft to successfully go around on a short final approach. The Civil Aviation Authority of Nepal has set stringent standards for pilots operating at this airport, requiring at least 100 short-takeoff-and-landing (STOL) missions, one year of STOL experience in Nepal, and ten flights into Lukla with a certified instructor pilot.
The history of plane crashes at Tenzing-Hillary Airport underscores its reputation as one of the world's most dangerous airports. Since 2000, there have been numerous incidents, with seven crashes occurring since 2000, resulting in over 50 fatalities. One notable crash happened in 2008 when Yeti Airlines Flight 103 crashed on its final approach, killing 18 passengers and crew. Other incidents include aircraft skidding off the runway, colliding with obstacles, and experiencing technical difficulties during takeoff and landing.
The airport's unique challenges have led to strict requirements for pilots operating at this airport. Captains must undergo special training, including a high number of short take-offs and landings, experience in similar conditions, and successful flights to Lukla with an instructor. Despite these measures, the airport continues to present a formidable test for even the most experienced pilots, earning its place as one of the world's most treacherous aviation hubs.

American Airlines crashes
While it is challenging to definitively state which airport has the most crashes, several airports have been labelled as dangerous due to their crash history and challenging conditions.
Tenzing-Hillary Airport, also known as Lukla Airport, is regarded as one of the world's most dangerous airports due to its short runway, high altitude, and surrounding mountainous terrain. The airport has a history of plane crashes and incidents, with challenging weather conditions and geographical constraints contributing to the difficulties.
Now, here is some information on American Airlines crashes:
American Airlines has experienced a significant number of crashes and incidents throughout its history. As of January 2025, the airline has recorded almost sixty aircraft hull losses, with the earliest recorded crash occurring in August 1931. Two of the most tragic accidents in the airline's history were Flight 191 in 1979 and Flight 587 in 2001.
On May 25, 1979, American Airlines Flight 191, a DC-10 aircraft, suffered an engine separation during takeoff from Chicago, leading to a loss of critical flight control systems. The aircraft crashed shortly after takeoff, resulting in the tragic loss of all 258 passengers and 13 crew members on board, as well as two people on the ground. This incident marks one of the deadliest plane crashes in history.
On November 12, 1995, American Airlines Flight 1572, an MD-83 aircraft, was on a scheduled domestic flight from Chicago to Hartford, Connecticut. The aircraft encountered issues and crashed about five miles short of the runway during a missed approach. Sadly, both crew members and 13 of the 18 passengers perished in the crash.
Another notable incident involving American Airlines occurred on July 11, 2024, when a Boeing 737 was forced to abort its takeoff at Tampa International Airport due to a wheel fire. Fortunately, there were no reported fatalities in this incident.
American Airlines has also been implicated in two of the most fatal accidents in aviation history, with Flight 11 and Flight 77 being hijacked and destroyed during the September 11 attacks. Flight 11 crashed into the North Tower of the World Trade Center, resulting in an estimated 1,700 deaths, making it the deadliest air crash ever recorded.
These incidents highlight the challenges and tragic consequences of aviation accidents, underscoring the importance of safety regulations and continuous improvements in the industry.

Short runways
One of the most notorious airports for its short runway is Lukla Airport (Tenzing-Hillary Airport) in Nepal. The runway is just 1,729 feet long (or 527 metres according to another source), far shorter than the typical runway length of 7,000-10,000 feet. The runway is also situated at a high altitude of 9,383 feet, surrounded by mountainous terrain, and ends in a 2,000-foot drop into a valley. The high altitude and unpredictable weather conditions mean that flights can only operate in the morning and are often cancelled due to snow or fog. The final approach and landing are considered the riskiest parts of any flight, and Lukla Airport's short runway, combined with its challenging location, make it a particularly dangerous airport.
Another airport with a short runway is St. Maarten's Princess Juliana International Airport, where the runway is just 7,100 feet long (or 7,150 feet according to another source). The short runway ends right on a public beach, and planes have to fly very low over tourists, creating a dangerous situation. In 2017, a woman died due to head injuries after being knocked over by the jet blast from a plane while standing by the airport fence.
Other airports with short runways include:
- Gustaf III Airport in St. Barths, with a runway of just 2,100 feet that ends on a public beach.
- Toncontin International Airport in Honduras, which has one of the world's shortest runways for big commercial jets at 7,000 feet, along with mountainous terrain and wind gusts due to high altitude.
- Aspen/Pitkin County Airport in the US, with an elevation of 7,800 feet and a history of multiple crashes due to ever-changing wind conditions, low visibility, and mountains on either side.
- Courchevel Airport in France, with a short runway of 1,788 feet that is also incredibly steep, with a gradient of 18.5% and a sheer rock-face drop at the end.
- Gibraltar International Airport, with a runway of 6,000 feet that is bisected by a busy road and surrounded by the sea on both sides, requiring pilots to navigate both air and car traffic.
- Alberto Carnevalli Airport in Venezuela, with a runway of only 1,630 metres situated in a valley between the Andean mountains.

Dangerous conditions
Tenzing-Hillary Airport, Nepal
Tenzing-Hillary Airport, also known as Lukla Airport, is located at a high altitude of 9,383 feet and is surrounded by mountainous terrain. The airport has a notoriously short runway of only 1,729 feet, which is significantly shorter than the typical runway length of 7,000-10,000 feet. The runway is situated on the edge of a cliff, with a steep drop of 2,000 feet on one side and a stone wall on the other. The weather conditions in the mountains can be highly unpredictable, with sudden snow or fog often leading to flight cancellations. Due to the challenging terrain and short runway, only small planes and helicopters are allowed to land and take off from this airport, and captains must undergo special training to operate in these conditions. Lukla has a history of plane crashes, with several incidents occurring over the years.
Kai Tak Airport, Hong Kong
Kai Tak Airport in Hong Kong, now closed, was once considered one of the most dangerous airports in the world due to its complex approach pattern. Planes approaching the runway had to navigate through high-rise buildings and make several sharp turns to align with the runway. This manoeuvre was notoriously difficult and earned the nickname "Kai Tak Heart Attack" among passengers.
Narsarsuaq Airport, Greenland
Narsarsuaq Airport in Greenland presents pilots with a unique set of challenges. Aircraft approaching the airport must fly through a valley-like fjord before making a sharp 90-degree turn to align with the runway. The surrounding mountains and strong tailwinds create severe turbulence, and icebergs can drift into the flight path, posing significant dangers to aircraft.
Saba Airport, Caribbean
Saba's airport is known for its extremely short runway, which measures only 1,312 feet in length. The runway is flanked by hills on one side and is in close proximity to the Caribbean Sea on the other. This leaves little room for error, as any miscalculation by the pilot could result in a plane plunging into the sea.
St. Helena Airport, St. Helena
St. Helena Airport, located on a remote British Overseas Territory in the Atlantic Ocean, was designed to improve accessibility to the island. However, strong wind shears create turbulent conditions that make it challenging for flights to land. The winds from the ocean hit the cliffs where the airport is located, resulting in a roller-coaster-like flight experience for passengers. Due to these challenging conditions, the airport was dubbed the "world's most useless airport."
Other Notable Mentions
- Aspen/Pitkin County Airport, USA: Located at an elevation of 7,800 feet, this airport has seen multiple crashes due to ever-changing wind conditions, low visibility, and mountains on either side.
- Alberto Carnevalli Airport, Venezuela: This airport has a short runway measuring only 1,630 meters and is situated in a valley surrounded by the Andean mountains. A crash in 2008 shortly after takeoff resulted in 46 fatalities.
