The sounds of fighter jets over Annapolis airspace Tuesday night came from a military exercise conducted by the North Aerospace Defence Command and Federal Aviation Administration, said Master Sgt. Tony Hill in the NORAD public affairs office.
The exercise, called Falcon Virgo, is a series of training flights designed to test NORAD's intercept and identification operations. Air Force F16's and Coast Guard helicopters were used, according to a news release on NORAD's Web site.
Exercises like these have been conducted since Sept. 11, according to the news release. The ones on Tuesday were conducted late at night and in the early morning in the greater Washington, D.C. region.
