England's sunny skies will be lit up by the incredible Red Arrows today.
Many will be treated to the fantastic display by the iconic planes as the jets practice a route to commemorate the 100th anniversary of the Royal Australian Air Force.
The trip will last just over an hour as they fly down from Scampton via Bury St Edmunds.
They head over Suffolk before passing over Hertfordshire.
Then the Red Arrows come into view in the capital, with people in west London most likely to catch sight of the incredible aircraft.
They pass Watford and Uxbridge just after 11am on their weather dependent route.

The near 650mph ‘practice’ formation flight will then head to Berkshire and Northampton.
Red Arrow pilots are due to land back at RAF Scampton at around 11am.
The planes were grounded on Thursday due to a Royal Navy jet crash in Cornwall.
