Thousands of people have gathered outside Buckingham Palace to watch a flypast of aircraft to mark the centenary of the Royal Air Force, BBC reports.
Up to 100 planes representing the RAF over the years flew over The Mall following a parade by personnel.
The Queen and other members of the Royal Family saw the display - which included the new F-35 fighter and Spitfires - from the palace balcony.
Earlier they marked the centenary at a special service in Westminster Abbey.
The service began what the head of the RAF said would be a "tremendous" day of events to mark its 100 years.
Three F-35 Lightning stealth fighters were involved in the flypast - the first time the aircraft has been seen by the public.
