Built 1954. This was a pioneering vertical take-off and landing aircraft developed by Rolls-Royce in the 1950s. It used two Nene turbojet engines mounted back-to-back horizontally within a steel framework, raised upon four legs with castors for wheels. It had no lifting or stabilising surfaces (wings, blades, etc.) and was commonly known as the ‘Flying Bedstead’. It joined the Science Museum in 1961 and is now on display in the ‘Making of the Modern World’ exhibition. Science Museum, South Kensington, London.
