The U.S.S. Macon was a potential money-saving answer for the US Navy at a time when The Great Depression made every penny count. It was a flying aircraft carrier that cost 75 times less to operate than a comparable surface cruiser. It was put into service in 1933 and less than a year-and-a-half later it had crashed into the Pacific Ocean with the loss of two lives.
