NORAD Flight Exercise Planned over Northern Virginia Tonight

If you hear or feel loud booms tonight, it's not an earthquake – it's F-16's.

From NORAD:

North American Aerospace Defense Command (NORAD) and its geographical component, the Continental United States NORAD Region (CONR), will conduct an exercise – Falcon Virgo 11-11 beginning Wednesday night, Aug. 24 at midnight into early Thursday morning, Aug. 25, in the National Capital Region.

Flights in the National Capital Region are scheduled to take place between midnight and 1:30 a.m. EDT Thursday morning. In the event of inclement weather, the exercise will take place the next day at the same time.
