The ERCO Ercoupe is a low-wing monoplane aircraft that was designed and built in the United States. It was first manufactured by the Engineering and Research Corporation (ERCO) shortly before World War II; several other manufacturers continued its production after the war. The final model the Mooney M-10 first flew in 1968 and the last model year was 1970. It was designed to be the safest fixed-wing aircraft that aerospace engineering could provide at the time, and the type continues to enjoy a faithful following.
