World War Two was probably the most documented event in all of human existence. US Army records weight 17,120 tons. That's about 188 miles of filing cabinets arranged side by side. Obviously, that is a lot of territory so my series is very succinct. The series is a mini-history with a focus on the air war, the men / women, the events and the times. I divided the book into very detailed sections. Example: Volume 4 covers the development of air to ground to support - the attack aircraft and dive bomber. I used the Spanish Civil War their being and accented their development in Burma. Some of the planes discussed include the A-24, -25, -27, -31/-35, and -35. Also talk about Howard Hughes' attempts to become a supplier of military aircraft - the A-37. The technology section discusses the development of aviation fuels and my home front section focuses on "their music. I commissioned several artists to create original illustrations and obtained permission of professional artist to use some of their work. I also used many images from government achieves. I researched my personal library, the internet, and the huge USMC Grey Research Center at Quantico, VA. I also consulted with subject matter experts in other nations, example Sweden and Germany. It is historical accurate, interesting and informative. I created the Little Friends series in part as a labor of love. My father, all eleven uncles, and a few first cousins were WWII veterans. I grew up listening to their experiences. As I said in the book, I certainly hope I've paid them proper homage.
