Both Typhoon flight passed over a few minutes ago, very audible but invisible despite a mostly blue sky. A couple of cumuluses (cumuli?) drifted across the best view, trees obscure most of thje rest.
Did see the SAM C-32; forget about the USN C-130T that just buzzed SE across London, didn't hear it.
Got a certain Cessna twin orbiting relentlessly overhead at the mo.
