Although the series is high in technical proficiency and detail to re-animate air battles, there is an almost complete of historical balance. The focus of most chapters is on American aviators as if they were repeating the "Mariana's turkey shot" through the ages. Only a few chapters are devoted to Israeli or German and Japanese odds-and-ends (Me-163, kamikaze, etc.). Almost no mention is done of German, Russian, Japanese, Chinese and even North Vietnamese Aces that top all-time aerial combat Aces lists. They even neglect traditional allies as the British and the French. There are very detailed accounts of aerial battles from the "other guys" point of view that should be included to have a really "Historical balance" of aerial warfare.
