Bill Gunston was a British aviation and military author. He flew with Britain's Royal Air Force from 1945 to 1948, and after pilot training became a flying instructor. He spent most of his adult life doing research and writing on aircraft and aviation. He was the author of over 350 books and articles. His work included many books published by Salamander Books.
A fun look at early 80s military aviation technology. Goes straight from 'spies are men in shabby raincoats and alluring women' to equations demonstrating how the distance we can see relates to height above sea level, then runs through the world's aircraft and a ton of acronyms (AEW, AWACS, OKB and so on). It's fascinating, now, to see the USSR's contributions represented as grainy photos and best guesses.
