Gloster E.28/39 W4041/G Prototype
The Gloster E.28/39, (also referred to as the "Gloster Whittle", "Gloster
Pioneer", or "Gloster G.40") was the first jet engined aircraft
to fly in the United Kingdom. Developed to test the new Whittle jet engine
in flight, the test results would influence the development of the Gloster
In September 1939, the Air Ministry issued a specification to Gloster for
an aircraft to test one of Frank Whittle's turbojet designs in flight. Working
closely with Whittle, Gloster's chief designer George Carter laid out a
small low-wing aircraft of conventional configuration. A contract for two
prototypes was signed by the Air Ministry on 3 February 1940 and the first
of these was completed by April 1941. On the 15th of May 1941, Gloster's
chief test pilot, Flight Lieutenant Gerry Sayer flew the aircraft under
jet power for the first time from RAF Cranwell, near Sleaford in Lincolnshire.
The flight lasted 17 minutes and was a complete success. The E.28/39 was then transfered to
Farnborough were additional finlets were added to the tail and it was repainted with ocean grey/dark green
The E.28/39 name comes from the aircraft having been built to the 28th "Experimental"
specification issued by the Air Ministry in 1939.
In 1946, the first prototype (Serial W4041) was placed in the British Science
Museum (London), where it is still exhibited, although in a scheme which it never flew in.
