Valetta at Cosford

This one?

Of course you all know that the Miles P6.36 Kestrel Trainer c/n 330 with its 745 hp R-R Kestrel engine and built at Woodley had excellent performance. It was first flown on June 3, 1937 and was the precurser of the Miles Master. It was later registered as G-AEOC but flew as U-5. Transferred to the RAF and given serial N3300 in May 1938, it was finally dismantled at Woodley in 1943.
But everybody knows that, don’t they!

There were 2 main reasons for abandoning the Hotspur:
1. The Boulton Paul Defiant, also designed to meet Spec. F.9/35 had flown by the time the Hotspur, after somewhat slow building, was ready, and
2. All the factories in the newly-formed Hawker Siddeley Group were fully committed to designs for which production contracts had been issued.
Note that the turret on the Hotspur was only ever a wooden mock-up and in fact was later removed, the gunner’s position being faired over , before this one and only prototype was used for Henley light bomber development trials at the RAE, where it remained from 1939 to 1942.

According to “Jane’s Fighting Aircraft of World War II” the Wellington length is 64 ft 7 in.
