A NORAD fighter jet intercepted an aircraft flying over Camp David’s restricted air space Saturday — and briefly caused concern with the president in town.

President Trump flew to the presidential retreat in Maryland’s Catoctin mountains Friday night, and is set to remain there through the weekend.

The First Air Force, which is part of US Northern Command, announced the intrusion on X.

“Pilots! @NORADCommand fighter aircraft intercepted an aircraft violating restricted airspace over Thurmont, MD, resulting in flares being deployed,” it said.

“Make sure to check NOTAMs before takeoff to ensure you have current information about TFRs in your area,” the post continued, referencing updates called Notices to Airmen.
