Call it a lesson learned.

After scaring residents on both sides of the Hudson River with a low-flying flight by Air Force One for a photo op in New York City, the military made a point today to announce upcoming flight exercises over Washington.

The North American Aerospace Defense Command said that between on May 15 and 19 between midnight and 6 a.m. a series of training flights would be held in the "National Capital Region."

The drill will involve the Federal Aviation Administration, the National Capital Region Command Center, the Joint Air Defense Operations Center, the Continental U.S. NORAD Region), Civil Air Patrol abd the Coast Guard, the Penta and CONR's Western Air Defense Sector.

Dubbed Exercise Falcon Virgo, the drill is designed to hone NORAD's intercept and identification operations and will include flights by Civil Air Patrol Cessna aircraft, two Air Force F-16s and one Coast Guard HH-65 Dolphin helicopter.

"Residents may see these aircraft approaching and flying in the vicinity of the Washington D.C. area as part of this exercise during the late night and early morning hours," the Department of Defense said.

So if you plan to be in Washington those days, don't be alarmed.
