The National Air and Space Museum, which was established in 1946, boasts the largest collection of historic aircraft and spacecraft in the world. With 23 impressive galleries housing hundreds of missiles, rockets, spacecraft and aircraft that showcase the history of flight, there are simply too many highlights to mention! Nevertheless, the must-sees include the Friendship 7 capsule that was flown by John Glenn, the inspiring Wright brothers' plane which kickstarted everything, the Bell X-1 and Charles Lindbergh's The Spirit of St. Louis.

Another highly recommended activity is to catch an astounding IMAX film on a five-story-high screen at the state-of-the-art Einstein Planetarium. Being surrounded by icons of space and travel, one would get to learn of the developments and chronicles of flight through the passage of time – an experience thought to be humbling yet extremely remarkable.
