This thread. Nah just kidding, I haven’t read any of the posts.
Seriously though, recently finished a book called First Blitz. It’s a historical book, describing the German plan to raze London to the ground with newfound air power in World War One. It was a pretty interesting book, starting with the token German aircraft dropping 3kg bombs in 1915 to the enormous Giant bombers unloading 1000kg bombs towards the end of the war. It was also quite amazing how ill-prepared England was for German air offensives and how the city of London narrowly avoided destruction by fire by only a few hours.
