Query: Pathetic drivel full of linguistic and technical errors.

Dorothy Parker wrote a review aeons ago which simply said "I put this book down and could not pick it up." Ditto with this nasty mess. The author has never apparently been near any of the military activities he presumes to portray, and it shows. The inaccuracies are so frequent and continuous that the mind reels. The book was given to me by an avid techo-thriller reader who said he didn't want it back and I could do what I wanted with it. I read about 20 awful pages and sent it on to a Naval aviator friend, a retired Rear Admiral and F-14 pilot, himself an excellent writer of books on naval aviation, who experienced the same cog-diss. Who accepts and publishes this sort of trash? It would make a bad doorstop or coffee coaster.
