DAYTON (AP) — The fabled World War II bomber Memphis Belle will finally go on public display next spring at the National Museum of the U.S. Air Force alongside John F. Kennedy’s presidential plane, an early Wright Brothers flyer and other national treasures. The journey from the flak-ridden skies over occupied France and Germany to restoration and display in the Ohio museum has been long for one of the most celebrated American planes to survive the war. The B-17F “Flying Fortress,” feted as one of the first to make it through the required 25 bombing missions, arrived at the museum at Wright-Patterson Air Force Base in pieces a dozen years ago.
