Leave it to Eric Sloane to create illustrations that convey so much information. His ability to do so did not go unnoticed early in his career. Several authors of pre-War II aviation books and articles tapped Eric as an illustrator, and the Army Air Corps published more than one training manual for pilots that made use of his illustrations.
