The Whittle 1 Jet Propulsion Engine, with one metal framed display notice, seen from 3/4 front view beneath the Gloster E28/39 in which it was installed. Sir Frank Whittle, while still a Cadet at Cranwell published a thesis entitled Speculation which put forward the basic thermodynamics for this, the first aircraft jet engine to run. In March of 1938 the Ministry gave Whittle a contract for an engine, and in May 1941 the Gloster E28/39 powered by this engine took off from Cranwell.
