The Smithsonian Air and Space Museum expanded the space by moving the larger airplanes to a hanger near the Washington-Dulles Airport in Chantilly, Virginia. It is a series of connected hangar-like structures designed to accommodate artifacts too large for the flagship building. More than 400 million cubit feet of space allows the center to display smaller aircraft suspended from the ceiling, each one angled as if in flight. The museum is the length of three football fields and is ten stories high!
