Bucharest-Henri CoandΔ Airport, also known as Bucharest-Otopeni Airport (IATA: OTP, ICAO: LROP), is the main airport serving the city of Bucharest, the capital of Romania. It is named after Henri CoandΔ (1886-1972), an engineer, scientist and pioneer of Romanian aerodynamics. In the area where the airport is located today there was a military facility with a 1,200-metre runway, used between 1940 and 1944 by the Third Reich Air Force and then, from the end of World War II to 1965 by the Romanian Air Force. In 1965, it became clear that Bucharest’s only civil airport, Bucharest BΔneasa Airport (now Aurel Vlaicu International Airport), would no longer be sufficient to withstand the increasing air traffic, and a new airport was decided. The choice fell on the existing military structure of Otopeni: the works lasted about 4 years and focused on the construction of the passenger terminal and the extension of the runway to 3,500 meters.
