North Atlantic air ferry route in World War II

The North Atlantic air ferry route was a series of Air Routes over the North Atlantic Ocean on which aircraft were ferried from the United States and Canada to Great Britain during World War II to support combat operations in the European Theatre of Operations (ETO). The route was developed as one of four major routes along which American and Canadian-built aircraft were ferried to the major combat areas.
