Man, I completely missed the news on the run up to this one:
Info taken from the RAF website:
"On 10 July, one hundred days after our official 100th birthday, join us in London for our centrepiece event, the RAF100 parade and flypast.
Over a thousand servicemen and women will take part in a parade on The Mall at 11:25am.
Her Majesty The Queen, accompanied by The Prince of Wales, will present a new Queen's Colour to the Royal Air Force at a ceremony to mark its centenary, on the forecourt of Buckingham Palace.
Then at 1:00pm The Queen, The Prince of Wales, The Duchess of Cornwall, other Members of the Royal Family and members of the public will witness the historic flypast where up to 100 aircraft, representing the RAF’s history, will fly over Buckingham Palace.
It promises to be a spectacle never seen before and one that won’t be seen again for a very long time.
HOW YOU CAN TAKE PART
Join us on the Mall and experience the celebrations in person.
Watch live coverage on BBC One from 9:30am to 1:20pm or stream on BBC iPlayer to watch the events as they unfold live. Alternatively listen to BBC Radio 2 for further coverage.

If you can't get to London but live in the surrounding area here's the route that the aircraft are taking in and out of London. So keep an eye (or two) on the skies so you don't miss out."
