Louis Caldera - now the former director of the White House Military Office - has been fired or quit over the recent flap where one of the Air Force One planes - together with two F-16s - buzzed New York City in an apparent "photo op" (link). It's somewhat difficult to believe that Obama or his top aides knew about and approved the incident, but it might be possible especially if there was an ulterior motive such as using this as a distraction or to keep New Yorkers on their toes.

UPDATE: The official White House report is in this PDF file.
