My compliments for the nice article on the Cold War ELINT missions near the Iron Curtain in the 1950's-60's, as can be found in the latest paper Scramble.
Very nice to read about these kind of hidden/forgotten operations.
As aviation news is 'hot' on the Internet, but already 'cold' when the Scramble is delivered by the mailman; these kind of background articles make a nice contribution to the paper Scambles.
