The book hangs together well, is well structured, laid out and with significant effort on technical images, which genuinely add to understanding. The research from various sources in various languages has clearly been thorough and detailed. Mr Douglas has written a tour de force here. I know many of the readers of this blog have a broader technical interest in military history.I “get” the importance of piston engine development at this period and had previously dipped into the subject a few years ago.This blog is essentially about the technical development of certain weapon technology – and this parallel weapon technology development to the matters I discuss on this site was pretty important.My father was a mech engineer and had a connection with Ricardo, a British engineering research company which played a key role, and also with Vickers who bought Supermarine in 1928.

When I say “refurbishing” I mean “tinkering and occasionally get it to spring in to life”.

Whoever designed the most powerful piston engines would win air superiority and with it the ability to dictate the course of the war as a whole. Advanced jet engines may have been in development but every militarily significant air battle was fought by piston-engined fighters.

The piston engines that powered Second World War fighters, the men who designed them, and the secret intelligence work carried out by both Britain and Germany would determine the outcome of the first global air war.
