Britain's Latest Jet Fighter -- Britain's latest experimental Jet fighter, the Hawker P.1052, which has been designed and built for the purpose of obtaining accurate aerodynamic measurements at speeds approaching that of sound. Developed largely from an earlier model, the P.1040, the new aircraft is characterised by its swept-back wings, which make it easily recognisable in the air. It is powered by a single Rolls-Royce 'Nene' engine. Performance details are still secret. July 20, 1949.
