Just inside the Mall entrance the Milestones of Flight hall, which just finished a renovation, gives a visual history of aviation by displaying Charles Lindbergh’s Spirit of St. Louis, the Bell X-1 in which Chuck Yeager broke the sound barrier, and the North American X-15. Don’t miss the Golden Age of Flight gallery, which includes Howard Hughes’s H-1 racer.
