Wolfe wrote that the book was inspired by the desire to find out why the astronauts accepted the danger of space flight. He recounts the enormous risks that test pilots were already taking, and the mental and physical characteristics—the titular "right stuff"—required for and reinforced by their jobs. Wolfe likens the astronauts to "single combat warriors" from an earlier era who received the honor and adoration of their people before going forth to fight on their behalf.
The 1983 film, The Right Stuff, is adapted from the book.
