This was a hard book to rate. It's a selection of anecdotes from NASA engineer Homer Hickam, which to varying degrees relate to his cat, Paco. The highlight is how Paco's meows help a sick astronaut feel better, thus allowing her to continue performing experiments on the Spacelab. Paco's claim to fame was he was the first cat whose meows were heard in space. While the anecdotes are cute, there's not a lot of meat to this 40 page book. Hickam is also the author of Rocket Boys, which was turned into the movie October Sky. Given the book's popularity, I assume it was put out by a major publishing house, not independently publishing loke Paco was. Paco definitely would have benefited from an attentive editor, as the book contains some significant errors: "I decided also to put one him in my novel....".; an incorrect number of victims mentioned in the 1984 sinking of the paddlewheel boat SCItanic; as well as numerous smallmissues involving commas and hyphen use. Still, it was a kind of cute story about a cat, so there's that. And I did learn some things about space shuttles.
