Once, they roamed the skies, keeping America safe from threats both at home and abroad. Now, the planes of the Wings of Freedom tour report for a different duty: educating future generations of historians. In keeping with its mission to educate the public on living history, The Collings Foundation takes these warplanes on the road, often near the airfield where they once served. Tour-goers may peruse vintage planes from the days of early flight and marvel at rare military planes from World War II, including a B-17 Flying Fortress bomber, a B-24 Liberator bomber, and a P-51 Mustang fighter. They can also study jets used in the Korean War, such as the North American F-100F Super Sabre and the F-4D Phantom, which was popular with pilots from the Navy, Air Force, and Marine Corps.
