Just serendipity, but I get a list of books that have gone on sale each day for the Amazon Kindle.
Today, Wolfe's The Right Stuff was $4.99. I jumped on it to replace the hardcover "loaned" to someone decades ago.
Be sure to read Deke Slayton's book (or books?) also -- he takes Wolfe to task about Gus Grissom's hatch malfunction, and spells out exactly why it must have been a malfunction.
