May Whittle, in second year at Cambridge, receives letter from R D Williams, with whom he had shared hut at Cranwell. This proposes a meeting with himself and his partner J C B Tinling, also an ex-RAF pilot. Agreed that Williams and Tinling try to raise £50,000 for Whittle to produce an engine, in return for each receiving a quarter share in the rights of the invention. Tinling introduces M L Bramson, a pilot and aeronautical engineer, who in turn introduces investment bankers.
Sept. Negotiations start with L L Whyte MC representing Falk and Partners, director Sir Maurice Bonham Carter also frequently present. Favourable technical report by Bramson, acting as consultant to Falk and Partners.

Falk and Partners to put in £2,000 with option on further £18,000 within 18 months. Director of Scientific Research asks for a write-up of engine (at Tizard’s prompting) to be sent to RAE for their opinion.

March Whittle receives Griffith’s negative report, which is considered by Engine Sub-Committee of Aeronautical Research Council. It concludes that Air Ministry should take up gas turbine research as matter of urgency. Result is that RAE authorized to go ahead, using Metropolitan Vickers as sub-contractors.
