On 9 July, Falk & Partners gave the company an emergency loan of £250. On 27 July, Falk's option expired, but they agreed to continue financing Power Jets by loan. Also in July, Whittle's post-graduate stay at Cambridge was over, but then he was placed on the Special Duty List so he could work full-time on the engine. On 1 November, Williams, Tinling and Whittle took control of Power Jets. Whittle was promoted to squadron leader in December. Tizard pronounced it "streaks ahead" of any other advanced engine he had seen, and managed to interest the Air Ministry enough to fund development with a contract for £5,000 to develop a flyable version. However, it was not until March 1938 that a contract was signed, when Power Jets became subject to the Official Secrets Act, limiting the ability to raise additional funds. In January 1938, BTH invested £2,500.
