Today we witnessed a glorious fly past of 100 aircraft as part of the RAF centenary.
Aircraft representing the RAF over the years flew over London, and Guildhall Yard filled with spectators.
The aircraft were led by helicopters, and included the Battle of Britain Memorial Flight as well as the new F-35 fighter.
Today the head of the RAF said it would be a "tremendous" day of events to mark its 100 years, and he was absolutely right.
Perhaps the most impressive part was the 22 Eurofighter Typhoons who spelt out 100 as they flew over.
Wonderful day to remember remarkable service.
