I love the book by George C. Kenny who in my opinion apart from Claire Chennault was one of the greatest air generals of World War II.The only reason why I gave it four stars was because there were a few things that General Kenny did not talk about a few things about Bong. I read the book Jungle Ace about Gerald Johnson and discover that Bong had lost three wingmen in three months and Bong swore that he would never fly with a wingman again. In the book, 49th Fighter Group by William Hess, I found out that Bong's aircraft was hit a few times in a number of engagements by the Japanese.
Positive
