Sigh… Don’t call me a fear monger okay. I’m going to present this in the most neutral way possible and I’ll let you decide. According to a news article, a sonic boom was heard over central England. The article is here. A helicopter mistakenly broadcast an emergency signal which prompted a swift response by the military. Two Typhoon jets were allowed to break the sound barrier to rush to the helicopter. The sound was heard over Bath, Swindon and Oxford.
So I did some digging on Youtube and to my delight I found a perfect recording of it from Bath. The only thing is, it’s not a boom but rather the jet sounds themselves. Notice how the jet roar suddenly stops and starts back up again. This occurred today at 6pm. It made the news immediately.
Here is the video.
When I viewed the above video I noticed she had linked to another video shot yesterday at 6am from the Netherlands. According to the poster of this video below, their local news said it was a broken air shaft of an electric factory. Go to the 11:55 mark and notice how it stops suddenly.
I will not comment on these as they have official explanations.
