Ben riches book is awesome and well worth the read. the best parts about that book were the stories from the sr71 pilots. my favorite being the reconnaissance officer's clearance code he gave to the French mirage pilots when asked.
I have a personally autographed copy of it. it sit's next to my Hugh Shelton and Paul tibbits personally autographed books in my collection.
