Air Botswana Corporation is Botswana's state-owned national flag carrier, with its headquarters located in Gaborone. It operates scheduled domestic and regional flights from its main base at Sir Seretse Khama International Airport. Air Botswana has been loss-making for several years, and there have been various attempts to privatise the company, and frequent changes to the corporation's management and board, so far without reducing the losses. History Formative years (1972–1986) Air Botswana (Pty.) Limited was founded on the 2nd of July 1972 to succeed two failed former national airlines: Botswana National Airways (1966–1969) and Botswana Airways Corporation (1970–1971). Air Botswana Holdings was responsible for the ownership and leasing of aircraft, and served as the holding company for Air Botswana. During the early formative years, Air Botswana (Pty.) Limited acted as a contractor for numerous flight services, which were contracted to South African Protea Airways, via a local subsidiary, Air Services Botswana. Flight operations began on 1 August 1972 utilising the only aircraft of the company: a Fokker F-27 Friendship. Throughout the 1970s, Air Botswana operated a round-trip route from Gaborone-Manzini-Johannesburg-Harare-Gaborone, in addition to domestic services to Francistown, Maun and Selebi-Phikwe. By the late 1970s, Air Botswana operated one HS 748, one Douglas DC-3 and one Vickers Viscount 754, the latter on lease from Protea Airways. The contract with Air Services Botswana for operation of the airline was not renewed, and in 1981 British Airways was awarded a contract for the operation of the airline for a six-year period. Also in 1981, Botswana Development Corporation was formed as a part of Air Botswana Holdings, with the corporation being tasked to acquire an aircraft for the airline to lease. The Fokker F27 was again chosen, and because of a lack of their own trained crews, the airline seconded crews from Comair and contracted maintenance out to Safair Freighters. In 1983 a Lockheed L-100-30 Hercules was leased and Air Botswana Cargo was formed to operate cargo charters, and when South African Airways ended services to Lesotho and Swaziland, a second F27 was acquired and services to Maseru and Manzini were inaugurated. A sixteen-seat Dornier 228-200 was leased in December 1984 from Kalahari Air Service, with the latter flying and maintaining the aircraft for Air Botswana. The 57 million pula Sir Seretse Khama International Airport opened on 10 December 1984, seeing Air Botswana operating from the airport. By the end of 1986, the route network
