Specialist book from one of war radar pioneers--Bawdsey, etc.
However Bowen made it readable--short manageable chapters, with anecdotes and narrative to enliven tecnhical side.
Bowen ranked as major scientist (with postwar radio astronomy and teaching career), so that gives more depth.
With respect to seller , price is stee---there is such a thing as library interlending!
