[Source]This Avro 707A was one of five built for flight testing as a part of the V-Bomber project, it was built to represent and test the aerodynamics of the Avro 698 Vulcan Bomber.
After their use in the RAF, this example was provided to the RAAF for aeronautical research.
Transfered to the RAAF 03/56 and arrived in Sydney 05/56 aboard the brand new aircraft carrier HMAS Melbourne. (It had already been resprayed overall silver with a black anti-dazzle panel from it's red colour scheme at this point),
Transfered to HMAS Sydney and shipped to Melbourne to begin its flight testing at Laverton VIC,
Operated by ARDU until 1963,
Sold in 1967 to Mr Geoffrey Mallett and transported to his home in Williamstown.
It was obtained by the RAAF Museum in 1999 and is currently on display there.
Curious thought....did they ever propose a fighter development of the 707?
My Dad flew the Avro 707s. He said they were enjoyable to fly and much data was collected.
