Oh wow! Gosh. This book has a lot of stuff that would meet this category. But one thing we’ve been telling people that’s just amazing - my wife did the research on this, we talked about crazy late 1950’s projects, but there was one called Argus. To keep it to a factoid, we detonated a bunch of nuclear bombs in space, and accidentally knocked out the first British satellite! It feels like a British comedy to me, they finally got their satellite up, and we shot it out of space. So when I think of a rarely told fact, I think of that.
