TopicRAF centenary: Thousands gather for flypast
Thousands of people are gathering outside Buckingham Palace to watch a flypast of aircraft to mark the centenary of the Royal Air Force.
Up to 100 planes representing the RAF over the years are due to fly over The Mall following a parade by personnel.
The Queen and other members of the Royal Family will watch the flypast from the palace balcony.
Earlier they marked the centenary of the RAF 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.
The flypast will be the first time the new F-35 Lightning will be seen by the public.

Nine helicopters will lead the armada, while the Red Arrows will bring up the rear.
The aircraft will assemble in holding patterns off the coast of East Anglia before merging near Ipswich and flying down the A12 corridor to London for the flypast.
