Anything by Buck is a good read. For those who don't know, Buck flew everything from DC-2s to 747s and logged over 2,000 Atlantic crossings. In WWII he flew a B-17 chasing hurricanes so he could fly through them to gather research data. "North Star" is fascinating autobiography.
His most popular is "Weather Flying," now being updated by his son, also Bob, and an important read for pilots.
I think most of the rest of his books are out of print but there are copies around. In addition to Weather Flying, I have:
North Star Over My Shoulder
The Art of Flying
The Pilot's Burden
Flying Know-How
Anyone knowing of any other books by him please let me know. I will hunt them down!
