VNLK Lukla Airport also known Tenzing–Hillary Airport is a small airport in the town of Lukla, in Khumbu, Solukhumbu District, Province No. 1, Eastern Nepal. The program Most Extreme Airports, broadcast on The History Channel in 2010, rated the airport as the most dangerous airport in the world for over 20 years. The airport is popular because Lukla is the place where most people start the climb to Mount Everest Base Camp. There are daily flights between Lukla and Kathmandu during daylight hours in good weather. Although the flying distance is short, rain commonly occurs in Lukla while the sun is shining brightly in Kathmandu. High winds, cloud cover, and changing visibility often mean flights can be delayed or the airport closed. The airport is contained within a chain link fence and patrolled by the Nepali armed police or civil police around the clock.
Lukla Airport is frequently referred to as the most dangerous airport in the world. Arriving and departing aircraft must use a single runway. There is a very low prospect of a successful go-around on short final due to the terrain. Due to the difficulties of successfully landing at the airport, the Civil Aviation Authority of Nepal sets high standards, for which only experienced pilots, who completed at least 100 short-take-off-and-landing (STOL) missions, have over one year of STOL experience in Nepal and completed ten missions into Lukla with a certified instructor pilot, are allowed to land at the airport…. On RW 06!…We are lucky as we have Len to certify us!!!
VQPR Paro Airportis located 6 km from Paro in a deep valley on the bank of the river Paro Chhu and is the only international airport of the four airports in the Kingdom of Bhutan. It requires pilots to have a special certificate before they can be allowed to land into Paro Airport due to the complexity (2011 there were only 8 qualified)! It is nestled among the steep mountains of the Himalayas and surrounded by natural beauty which makes flying to Paro quite the scenic experience. Deep in a valley 2,235m (7,332ft) 1.5 miles above sea level with surrounding peaks as high as 5,500m (18,000ft), it is considered one of the world's most challenging airports if not one of the most dangerous in the world. Even the runway is just 6,500ft long - one of the few runways in the world that the elevation is shorter than their height above sea level.
Flights to and from Paro Airport are only allowed under VMC and are restricted to daylight hours between sunrise and sunset. Despite the perilous conditions, the views over the clear blue waters over the Paro River and the lush green foliage of the Himalayas are breath-taking. Anybody flying to Paro must first land in neighbouring countries then catch a connecting flight. Planes have to weave through the dozens of houses that are scattered across the mountainside - coming within feet of clipping the roofs. Strong winds whip through the valleys, often resulting in severe turbulence.
