Let'em Breathe Space is a science fiction story by Lester del Rey. Excerpt from the book: "Eighteen men and two women in the closed world of a space ship for five months can only spell tension and trouble—but in this case, the atmosphere was literally poisoned. Five months out from Earth, we were half-way to Saturn and three-quarters of the way to murder. At least, I was. I was sick of the feuding, the worries and the pettiness of the other nineteen aboard. My stomach heaved at the bad food, the eternal smell of people, and the constant sound of nagging and complaints. For ten lead pennies, I'd have gotten out into space and tried walking back to Earth. Sometimes I thought about doing it without the pennies. But I knew I wasn't that tough, in spite of what I looked."
