 Over eleven months, the tests with 50° and 60° sweep were concluded with the high tail configuration.In January 1954, the low tail rear fuselage was fitted and tests continued for a further two years and proved that the EEC configuration was correct.After completion of its test programme, the SB5 eventually joined the fleet of the Empire Test Pilots' School (ETPS) at Farnborough in 1967, as is evidenced by the ETPS 25th Anniversary brochure in 1968.
