Dan-Air was an airline based in the United Kingdom and a wholly owned subsidiary of London-based shipbroking firm Davies and Newman. It was started in 1953 with a single aircraft. Initially, it operated cargo and passenger charter flights from Southend (1953–1955) and Blackbushe airports (1955–1960) using a variety of piston-engined aircraft before moving to a new base at Gatwick Airport in 1960, followed by expansion into inclusive tour (IT) charter flights and all-year round scheduled services. The introduction of two de Havilland Comet series 4 jet aircraft in 1966 made Dan-Air the second British independent airline after British United Airways to begin sustained jet operations.

The BAC One-Eleven is an early jet airliner produced by the British Aircraft Corporation (BAC). Originally conceived by Hunting Aircraft as a 30-seat jet, before its merger into BAC in 1960, it was launched as an 80-seat airliner with a British United Airways (BUA) order on 9 May 1961. The prototype conducted its maiden flight on 20 August 1963, and it was first delivered to BUA on 22 January 1965. The 119-seat, stretched 500 series was introduced in 1967. Total production amounted to 244 until 1982 in the United Kingdom and between 1982 and 1989 in Romania where nine Rombac One-Elevens were licence-built by Romaero.
