If you’re up late or an early riser, you could see or hear military aircraft over the D.C. region early Wednesday.

The North American Aerospace Defense Command, or NORAD, plans to run a live-fly air defense exercise between midnight and 2 a.m. Wednesday.

Aircraft that could fly overhead during the exercise, called Falcon Virgo, include F-16 fighter aircraft, U.S. Coast Guard MH-65D Dolphin helicopter, U.S. Air Force UH-60 helicopter, and Civil Air Patrol C-182 aircraft, NORAD said.

Some of the aircraft may fly as low as about 1,000 feet and can be visible from the ground. Weather may play a factor, and in case of inclement weather, the exercise will be pushed to the next day at the same time.
