Boys' Book(s) from the start of World War II. Echoing similar series from WWI; in fact the inside covers of some printings show WWI biplanes.
Easy reading. No real plot complications. A lot of action scenes; hard to believe our boys survived so many books so full of wartime dogfights. In reality the life of a fighter pilot was short.
Fun characters:
“O'Malley looked at the pie counter but shook his head. Five pies in one afternoon might spoil his dinner and he planned to enjoy a real feed.”
Accuracy: there's details we know are wrong. Actually the author read extensively to get it as right as possible. But there was a war on and many published details were deliberately misleading. "..with the RAF" starts with a test pilot for Hendee and their new Hawk. This is based on the hush-hush P-47 Thunderbolt, but only as far as had been revealed in 1941. Sometimes he "kicks" the throttle (airplanes use hand-throttles). In "..Italy" they fly the de Havilland Mosquito, which really had two V-12 engines, but here it has radials and at one point, only one engine. The Mosquito was indeed too fast to catch and was often armed as the book says. However he puts way too many people aboard for the rescue scene.
Facts aside, the stories are well-told. The author wrote a lot of western adventures, as well as aviation books and spy stories.
A very fun read and re-read from my childhood.
