PETERSON AIR FORCE BASE, Colo. (AP) - The North American Aerospace Defense Command is conducting training flights over the Florida Keys.

NORAD says aircraft will practice interception and

identification procedures Tuesday afternoon, weather permitting.

People who live near Naval Air Station Key West may see or hear fighter jets near another aircraft playing the role of a "track of interest."

NORAD, based at Peterson Air Force Base, Colo., is a joint U.S.-Canadian command that patrols the skies over North America.
