The Junkers F 13, a revolutionary all-metal passenger aircraft, was built shortly after World War I. This innovative plane, with its metal fuselage and wings, was a major leap forward in airplane design. Hundreds of F 13s were built and used around the world for over 30 years, making it a highly successful commercial airplane. Today, you can see some of the original F 13s in museums, and even a new replica is flying again.
