We Seven could have been a wonderful book. It’s a collaborative work by the Mercury astronauts, telling about their experiences as some of the first people in space.
I heard of its existence several years before I was able to find a copy. Then, reading it, I realized that there are very good reasons that Tom Wolfe’s version of the events in The Right Stuff sold millions of copies and this one went out of print.
The story’s still great, but go with Wolfe’s version—evidently NASA’s training program didn’t involve a creative writing component.
