The National Air and Space Museum opened its main building on the National Mall in 1976.
The Air and Space Museum is just beyond the Hirshhorn Museum and Sculpture Garden on the National Mall.
In 2018, the Air and Space Museum saw approximately six and a half million visitors, making it the fifth most visited museum in the world.
Things you would want to see might be Friendship 7, the capsule flown by John Glenn in February in 1962, or perhaps The Spirit of Saint Louis, the plane that in 1927, Charles Lindbergh flew when he became the first to fly solo non stop across the Atlantic Ocean from New York to Paris France.
