The Society of British Aerospace Companies (SBAC, formerly Society of British Aircraft Constructors) was the UK's national trade association representing companies supplying civil air transport, aerospace defence, homeland security and space.

[2] With its regional partners, SBAC represents over 2,600 companies, assisting them in developing new business globally, facilitating innovation and competitiveness and providing regulatory services in technical standards and accreditation.

Inside the organisation is the British Aviation Group and the UK Space Agency.

They were also instrumental in approaching Lloyd's of London to start the inspection and insurance of aircraft, which led to increased commercial aviation.

[3] The Farnborough shows were held annually as trade fairs for British manufacturers and with two public days, the Saturday and Sunday, throughout the 1950s.

In 1962 the British-only rule was slightly relaxed by allowing the participation of foreign aircraft with British engines.
