The book is about the early P2Yand PBY designs that involve the Consolidate Aircraft Factory during the late years of 1920s. Consolidated aircraft was the first designed under the chief aero-engineer, Isaac Mackin Laddon. He joined the Consolidated Company in 1927. The Consolidated founder was Reuben H. Fleet who was a primary trainer-built company from the US Navy and US Army Aircraft. He wanted to extend his business to a multi-engine aircraft with designer Igor Sikorsky. The company plant was originally located in Buffalo, New York, but later moved their plant to San Diego, California. They both headed a team of engineers to design a long-range flying boat under the contract to the Boeing Company which later serviced the US Navy during World War I. Consolidated Company was very influential in the PBY aircraft design in saving many down pilots during the war.
