A branch of the famed Aid and Space Smithsonian Museum, it houses many aerospace marvels and milestones that have not found a home on the National Mall. In addition to many less well-known machines such as the SR21, Superconstallation, Concorde, F14, F35, FW190, etc., the Space Shuttle Discovery is also in its own hall together with a number of satellites. Even if the location can actually only be reached by Uber/Lyft, it is a must for all enthusiasts. ENTRY is FREE!
