An amateur cameraman has captured the moment a presidential jet and a fighter plane flew low over New York, sparking panic among office workers.
The half-hour flight triggered the evacuation of a number of office buildings in the city - Mayor Michael Bloomberg said he was "furious" he had not been warned.
The White House has apologised for the incident.
The president was not on board the flight, which was organised to take photographs of the presidential jet against the New York skyline
