Yesterday (13th) morning around 09:00 - something noisy (multi-jet) heading north and climbing over Cheltenham, probably out of Brize Norton/Fairford. It was too cloudy to see and nothing was showing on FR24, but given the prolonged volume I guessed B52(s). A local Facebook page later indicated that they were B1B Lancers, which returned later in the morning while I was elsewhere.
It sounded like they went over again this morning around 08:10, but again it was too cloudy to eyeball them.
