Don't worry A.T.C.S - poor old A.C. Kermode popped his clogs some years back and a couple of other guys are editing his books. So those commission cheques aren't even in the post yet...
It seems funny to me that there is a new edition about once a year and the only thing that changes is the photo on the cover! Although they have improved the appearance of the text and some diagrams.
I can also rate 'Flight without Formulae' as a good intro and then 'Mechanics of Flight' once you're ready to impress with your knowledge. Heavy reading some of it, but it's spot on.
