To hear it from the horse鈥檚 mouth, check out Pioneers of Radar.
Colin Latham and Anne Stobbs have written the history of Britain鈥檚 development
of radar based on the memories of the hastily assembled teams of scientists, and
it鈥檚 always interesting, sometimes thrilling. It鈥檚 a pity that the book has an
old-fashioned layout and murky illustrations, but if you stick with it you鈥檒l
get it all鈥攖he crises, the successes and the lucky breaks against the
background of a war that Germany may have begun with a lead in technology. Not
least of these breaks came in August 1939, when a Zeppelin sent along the east
coast of England failed to detect radar beams. Published by Sutton,
