I thought he ranked them Spit XIV, Fw 190 D-9, P-51D in that order.
Actually on page 208 (Duels in the Sky) he lists the the greatest single-seat fighters in the order;
1. Spitfire and Fw190
2. F6F Hellcat
3. Mustang IV (P51D)
4. A6M5 Zeke
5. Tempest V
6. N1K2-J George
Since he has flown all of them who are we to question the pick.
However, I think he may have a bias against the P-51D for I quote from page 208; " Next one must look at the American fighters, and here is it easier to make a judgement. In the Far East the Hellcat almost single-handedly turned defeat into victory. The Mustang IV, though technically superior, never made an impact on any war theater." OMG......Ooops!!!! I can see how a naval pilot could have that thought.
