Original District of Columbia ADIZ
The original Washington ADIZ was somewhat larger and was roughly co-extensive with the Class B airspace around Washington. On August 30, 2007, the ADIZ was changed to a circle surrounding Washington, D.C., with a radius of 30 nautical miles (60 km), with a small triangular cutout for Leesburg Executive Airport. This change reduced the size of the ADIZ by 1,800 square miles (4,700 km2) and removed 33 airports from its coverage.
