Closure
Washington-Hoover Airport closed as a public use airport in 1941 when Washington National Airport opened on June 16, 1941. After transfer of passenger and air transport flights to National, Washington-Hoover was used as a private field by a pilot training school.
In late June 1941, the Army selected Washington-Hoover for the site of a proposed $3 million supply depot. The supply depot was never built; instead, The Pentagon was constructed on the site of the old airfield. In June 1941, Congress finally appropriated money for the purchase of the airfield for military use. On September 16, 1941, the War Department bought Washington-Hoover Airport for $1 million for construction of The Pentagon.
The Goodyear Blimp moved to National Airport in November 1941. Ground was broken for the construction of The Pentagon on November 8, 1941, and Washington-Hoover ceased to exist.
