Skunk Works: A Personal Memoir of My Years at Lockheed by Ben Rich is really good
"That damned Swede can actually see air."
He spent some space talking about the U-2 and that material is the kind of thing I had in mind when talking about how the book gives an impression of Kelly Johnson. For example, prior to reading the book I didn't know that while the CIA people expected downed pilots to kill themselves, Kelly Johnson thought that was nuts, was sympathetic to Francis Gary Powers, and gave him a job as a test pilot when he returned from captivity.
I think the book is well written and accomplishes a lot with small anecdotes like that one. It was a lucky find for me. I pulled it off a bookshelf in an airport convenience store because it was the only book that didn't look insanely boring.
