The PB2Y Coronado was a large flying boat patrol bomber designed and built by the Consolidated Aircraft Co., San Diego, CA, and used by the US Navy during World War II in bombing, antisubmarine and transport roles. Of the 217 built, ten were provided to the British Royal Air Force (RAF) serving with the RAF Transport Command. Four were transferred to the U.S. Coast Guard base located in San Francisco, CA. Coronados also served as a major component in the Naval Air Transport Service (NATS) during World War II in both the Atlantic and Pacific theaters, being flown by Pan American Airways (Pan Am) and American Export Airlines, Inc. Obsolete by the end of the war, Coronados were quickly taken out of service. Only one example remains and can be seen at the National Naval Aviation Museum at Naval Air Station (NAS) Pensacola, Florida. Each of the 217 Coronado Bureau Numbers (BuNos) is represented by some piece of its history within this book.
