"is Shaws book worth $60.00 canadian?"
Yup.
It's filled with first person accounts, quotes from the big boys of air combat from 6 decades of war in the skies, many many many diagrams of fights, their evolvement, their outcomes...
In short; this is the BIBLE of ACM. It teaches SA, energy, position, gunnery, dissimilar and similar ACM tactics, 1v2, 1v1, 2v2, section tactics.. all of it. In as much detail as you can assimilate. It can be (and will be if you are serious about becoming GOOD) read HUNDREDS of times, with each re-read producing more valuable knowledge and insight into the total experience of ACM.
