Sonic Boom at 1100 today?
What was it today, anyone dare day? Set off loads of house and car alarms over the NE of England, I couldn't believe how many were set away - bizarre really. I could see a single very high vapour trail, very high....heading NW, or West. Sky was clear today. A few big airliners followed about 20 minutes later, also high. And they looked completely different and bigger in their trails.
Anyway, good effort. Just curious, brother rang me about it, people are patriotic up here about these things but it was very unusual.
