In an intelligence community context, the American spy satellites like the KH program achieved astonishing things in photography, physics, and rocketry—things like handling ultra-high-resolution photography in space (with its unique problems like disposing of hundreds of gallons of water in space) or scooping up landing satellites in helicopters were just the start. (I was skimming a book the other day which included some hilarious anecdotes—like American spies would go take tourist photos of themselves in places like Red Square just to assist trigonometry for photo analysis.) American presidents obsessed over the daily spy satellite reports, and this helped ensure that the spy satellite footage was worth obsessing over. (Amateurs fear the CIA, but pros fear NRO.)
What is that book with the fun anecdotes?
