February - A group meets to study the supersonic transport (SST) concept for the first time. Arnold Hall, director of the Royal Aircraft Establishment (RAE), asked noted aeronautical engineer, Morien Morgan, to form a committee to study the concept.
April - Morgan’s committee deliver their first report. The group considered the concept of an SST unfeasible, and instead recommended continued low-level studies into supersonic aerodynamics. Not long after Johanna Weber and Dietrich Küchemann at the RAE publish a series of reports on a revolutionary new wing planform known as the ‘slender delta’ concept, showing that a thin delta wing with a high angle of attack could generate sufficient lift for take-off and landing of a supersonic airliner.
November - The UK sets up a committee to study the feasibility of supersonic passenger aircraft. The Supersonic Transport Advisory Committee (STAC) included officials and experts from government departments, airlines and aircraft manufacturers.

March - STAC report recommends the UK develop long-range supersonic transport with design studies for two supersonic airliners, one to fly at a speed of Mach 1.2 and the other at Mach 2.0 (twice the speed of sound). Bristol Aeroplane Company and Hawker Siddeley Aviation are commissioned for the preliminary designs, which are developed as the HSA.1000 and Bristol 198. The government and the STAC group look for major partners to help develop the designs.
September - Hawker Siddeley approach American aerospace company, Lockheed Corporation.
