It is a big moment many will be waiting for during the King's coronation - the Red Arrows flypast over Buckingham Palace always amazes, even if Prince Louis found them a little too loud during the Jubilee celebrations last year.
There is a plan for a flypast on the afternoon of Saturday, May 6, but the Ministry of Defence has already warned that it might have to be scaled back, or even cancelled in poor weather.
Forecasters expect conditions in London to be cloudy and wet on Saturday, which could hamper the ability of pilots to fly safely. You can find the coronation weekend forecast here.
