The B-17, developed in the 1930s, is a classic symbol of the US Air Force. It was nicknamed the “Flying Fortress” because of its many machine gun mounts. Only a few of these historic aircrafts survive today. In this model, you can explore the entire body of the plane, including the cockpit, bombardier’s seat, radio room, and the fuselage.This particular aircraft was restored to wartime configuration by the The Collings Foundation. It is named “Nine-O-Nine” in honor of a 91st Bomb Group, 323rd Squadron plane of the same name which completed 140 missions without an abort or loss of a single crewman. Today, she flies as part of the Wings of Freedom tour.lThe Collings Foundation organizes living history events to help Americans learn more about their heritage through direct participation.
