Built from an engine nacelle from RAF VC10 XV104.
The VC10 and Super VC10 were flown by BOAC (later British Airways), a small number of other airlines and the RAF.
Some of the RAF aircraft were used as air-to-air refuellers and a number of redundant BA examples were also acquired by the RAF.

The VC10 was a fast and popular passenger jet but never sold in large numbers. It was also hellishly noisy.
Here's an example being flown into Bruntingthorpe airfield and aviation museum.
