Was abruptly woken up by a very loud bang / explosion noise at roughly 4am. Apart from my dog, I was the only one to hear the noise in my household so went back to bed thinking I was losing the plot. That or the few glasses of wine I had the night before were playing with my mind. Turns out I wasn’t actually losing it, and a large number of people on Twitter were questioning this weird morning tremble and it seems to be the result of a sonic boom from a fighter Jet responding to an unknown aircraft. What’s even more weird is some people could hear it as far as Essex, Cambridge and in some reports Wales, yet my family didn’t hear the damn thing, even though it felt as if a nuclear bomb had hit nearby. Anyone else in Watford hear it?
