Look to the skies, as the Red Arrows will fly over London on Saturday (15th Aug 2020) in the late-afternoon.
The route is also an unusual one, coming in from the South-West, over Richmond, then Chelsea, and likely to then heading over towards North-East London towards their next turn point near Chelmsford in Essex.
The flypast over Richmond is due at 5:28pm, Chelsea at 5:30pm, and seconds later, over central London.
The Chelsea flypast coordinates look to be centred on the Royal Hospital, aka, the Chelsea Pensioners, so the flypast by red aircraft will be watched by the men and ladies in red on the ground.
Although the reason is not specified, the flypast is almost certainly part of the commemoration events for Victory over Japan Day (V-J Day) which took place on 15th August 1945 — 75 years ago.
The full NOTAM is below – the times are in GMT, so add an hour for British Summer Time.
