NORAD Calibration Flights Scheduled Tuesday

The North American Aerospace Defense Command and the Federal Aviation Administration will be flying four small radio-controlled planes and four Light Sport Aircraft near Quantico this week.

NORAD announced Monday that these calibration flights will take place March 20-23 from 8 a.m. to 5 p.m. The planes and radio-controlled craft will be flying 150 and 3,000 feet above ground level.

"Additionally, a Beechcraft C-12 aircraft will fly patterns at approximately 1,000 feet and 18,000 feet above ground level. These flights have been carefully planned and will be closely controlled," said NORAD in a press release. "The flights are intended to assist in calibration of systems and equipment, and will serve to refine and improve our ability to respond to unknown and potentially threatening aircraft."
