The North American Aerospace Defense Command says two general aviation aircraft were escorted away from Camp David by F-15E fighters on Saturday: one shortly after noon, and the other just before 7 p.m.
A third airplane, a Cessna 182, was escorted from Camp David around 10:30 a.m. Sunday. The fighter jets were dispatched because the small planes were out of radio communication.
President Obama spent part of the weekend at Camp David with his family before returning to Washington Sunday to continue talks on a debt-reduction deal.
A NORAD spokesman says all three airplanes landed without incident and there was no apparent connection between the three flights.
