Walking home this evening as it was getting pretty dark (what a sunset!), heard what sounded very much like a pair of Gipsy Queens - had to have been a Dove! Heading west from the Biggin Hill direction, probably overflew Kenley. All I could see was the anti collision beacon winking seductively...
Wow, that is very impressive aircraft recognition, it being pitch bloody dark at the time, it was indeed a Dove, G-OPLC.
