I'm sure years ago it was quite common to hear the sonic boom of concorde if you were just a few miles offshore at sea. I'm sure it was a daily event... Maybe my memory is playing tricks but I seem to remember people roughly taking the time from the boom.
Strange, was in Cambridge yesterday came home this morning mrs said it sounded like a bomb,
When I was up north earlier in the year near a place called Chollerford two American stealth bombers flew over us, it sound like a bomb going off over your head , mrs took the piss then when I told her.
Can’t believe they would fly something similar over london for no reason.
