Failure is not an OptionThe first time I heard this sentence is when I saw the movie Apollo 13 (Tom Hanks), when I was only 7 years old. I then read the book only when I was 11 years old. Gene Kranz is a great writer as well as a great Flight Director.The book explains about everything from Mercury, through Gemini, to Apollo in great detail. The book taught me a lot of stuff that I did not know such as that Gemini 7 was before Gemini 6A. The book explains why did it happen and how. It will also explains what they were going to do about it.The book has 21 pictures and 397 pages of knowledge. I recommend it for everybody
