“Smithsonian officials yesterday showed off their next museum, a facility so big it could swallow the Titanic, with space left over. The new building is part of the National Air and Space Museum annex near Dulles International Airport that will give the public a close-up view of more than 200 historic aircraft — from sleek spy planes to World War I biplanes. [The exhibition space is] a cavernous structure 10 stories high and covering the equivalent of three football fields.”
