OK. Biggles (Google him) is my name for the occasional low flying military jets that scream through the sky above Llandysul, and most other parts of Wales from time to time. There are usually two of them, hence the reference to his mate Ginger.
It's only occasionally, but incredibly loud and disconcerting.
I've only ever experienced this during daylight hours, but tonight, for the first time ever, the came over1 after dark.
Something new?
1 OK. Not actually over.
