Potomac Airfield (VKX) near Washington, D.C., has reopened.
The TSA closed the airport in November, claiming Airport Manager David Wartofsky was not following TSA-approved security procedures established in 2002 for the three airports in the Air Defense Identification Zone (ADIZ). Wartofsky countered the measures that were used at Potomac went beyond the scope of those required by the TSA.
Potomac was reopened after Wartofsky implemented the TSA-approved plan and demonstrated that the procedures were being followed.
