Earlier today (July 10), 100 planes travelled across the skies to mark the 100th birthday of the Royal Air Force.
Among the incredible flypast were three of the RAF's new F-35 Lightning stealth fighters, which was the first time the aircraft has been seen by the public.
The occasion concluded with 22 Typhoons spelling out '100' as they flew over Buckingham Palace, and then the Red Arrows flew over London.
You can watch the entire flypast - taken from Smooth HQ's roof - in the video above.
