The North American Aerospace Defense Command (NORAD) acknowledged the incident in a pair of tweets on Wednesday afternoon, not long after the illicit flyover was caught on film during the Trump rally.

“At approx. [2pm] NORAD F-16 aircraft investigated a general aviation aircraft that was not in communication with [air traffic control] and entered the Temporary Flight Restriction area surrounding Bullhead City, AZ without proper clearance,” the agency said.

The violating aircraft was non-responsive to initial intercept procedures, but established radio communications after NORAD aircraft deployed signal flares. The aircraft was escorted out of the restricted area by the NORAD aircraft without further incident.
