One witty pilot.

Fox News' Jim Angle, who was on the flight with the president, said that at one point, the plane's security was jeopardized when a British Airways pilot crossed the path of Air Force One and inquired if that was indeed the president's plane.

"The Air Force One pilot paused for a few moments and then said, 'No, it's a Gulfstream 5,' which of course is a small private plane, a fraction of Air Force One. The British Airway pilot obviously recognizing that sometihing was afoot said, 'Oh,' and let the matter drop," said Angle, who was the White House pool reporter on Thanksgiving Day, charged with following the president wherever he goes.
