WASHINGTON - If you hear and see military aircraft early Wednesday, it's just a drill.

The North American Aerospace Defense Command is conducting its training flights over the Washington region until 5 a.m. The exercise is designed to hone NORAD's ability to intercept planes.

Civil Air Patrol aircraft, Air Force F-16s and a U.S. Coast Guard HH-65 Dolphin helicopter will participate.

Since Sept. 11, 2001, NORAD flights have responded to more than 3,400 possible air threats in the U.S.
