Boeing 247D DZ203
This aircraft, originally Boeing serial 1726 and known as NC13344 while in service with United Airlines, was purchased by the Canadian National Research Council (NRC) before WWII, where it became CF-BTA and then RCAF 7655. As part of the Tizard Mission, an aircraft was to be fit with US versions of the British radar systems, but a US built aircraft was not available, so the NRC offered 7655. After test fitting the systems in Canada, the aircraft was disassembled and shipped to the Liverpool Docks in July 1941. The aircraft was re-assembled and became DZ203.
DZ203 spent most of the war as part of the TFU experimental flight of the Telecommunications Research Establishment, the Air Ministry group developing airborne radar systems. It was flown primarily from RAF Defford after May 1942, after brief periods at Christchurch and Hurn, following the TRE as it moved about the UK during the war. It was used extensively over the Irish Sea
In 1944 the aircraft was completely refurbished as a testbed aircraft for instrument landing systems. In June 1944 it was shipped to the US to fit an all-electric autopilot and American blind landing equipment, returning later in the year. The aircraft was actively used in this role until 1946, but was scrapped in 1947.
