Really not impressed with Hayne's lineup this year. They had a whole bunch of great "workshop manuals" last year on vehicles like the B-24, Churchill tank, Empire flying boat, Vickers Wellington, and the Apollo 13 spacecraft. I've only bought two new books from them this year - one on the
Queen Mary 2 which had some cool material but felt like a big promotional puff piece from Cunard, and their book on Spitfire restoration, which again, had some cool stuff in it, but tried to cram too much in too short a book.
I used to be addicted to these Haynes "manuals," but I'm starting to think the honeymoon period is over...
