Hunting Aircraft was a British aircraft manufacturer that produced light training aircraft and the initial design that would evolve into the BAC 1-11 jet airliner. Founded as Percival Aircraft Company in 1933, the company later moved to Luton, UK. It was eventually taken over by the British Aircraft Corporation (BAC) in 1960.

Vickers-Armstrongs Limited was a British engineering conglomerate formed by the merger of the assets of Vickers Limited and Sir W G Armstrong Whitworth & Company in 1927. The majority of the company was nationalised in the 1960s and 1970s, with the remainder being divested as Vickers plc in 1977.
