I've read lots about the Apollo program, and it's so remarkable that in about 8 years we went from a suborbital flight in a Mercury capsule, through the Gemini program to the Apollo 11 landing. "Moon Shot" was an exciting read, as well as "Men From Earth", "Lost Moon", and "Apollo 8". I also like the TV documentary "Moon Shot" that has lots of footage of the program and interviews with the astronauts. Can watch that one on Youtube.
