On 29th March of this year, The Society of British Aerospace Companies celebrated the completion of fifty years' activity. It was on 29th March 1916 that The Society of British Aircraft Constructors was incorporated —junior to The Royal Aeronautical Society and The Royal Aero Club, but senior by two years to the Royal Air Force. The Society continued under that title until 26th February 1964, when its name was changed to “Society of British Aerospace Companies.” The new title retains the well-known initials SBAC but more accurately covers the wide range of interests of the Society's Members—not only the manufacture of aircraft, but of engines, missiles, electronics, hydraulics and pneumatics, electrical equipment and all other components and materials essential to such a technologically advanced industry. The new title also brings the Society into line with comparable associations in the United States, France, Germany, and Italy.
