Nah, I was in Purley, NtKB, looking south - The aircraft must have been west of the Midhurst area, just out of view behind the treeline to me.
You are right about the Olympic rings, maybe Boris had somebody orbiting to add a little something to his mass cycle ride down to Dorking.
Hopefully someone down West will have had the binos out and seen what it was...
Or perhaps they've all be Chemtrailed...
