National Air & Space Museum is great for everyone, from infants to grandparents. Babies love the aircraft suspended from the ceilings like massive mobiles (including the Spirit of St. Louis, which Charles Lindbergh flew solo across the Atlantic and the plane that broke the shound barrier, the Bell X-1 Glamorous Glennis). Older children and grown-ups can explore exhibits on astronauts — living quarters, learn what their weight would be on Jupiter (or Mars), touch a moon rock, or watch an IMAX film. New addition, America by Air chronicles the history of commercial air travel from the earliest days of airmail to the advancements of the 21st-century jet age. Stories and activities just for preschoolers take place in the Barron Hilton Pioneers of Flight gallery.

The National Air & Space Museum is one of the Smithsonian museums — which are all free. It is also located adjacent to the National Mall, which is home to many memorials, monuments and museums.
