I'm sure people remember those odd groaning/screeching/trumpet sounds that were seemingly coming from the Earth in various locations around the world a few years ago.

I'm yet to hear of an explanation for them. To me, they sound very mechanical, like heavy industrial machinery and I saw a comment somewhere referring to a video that made the link between tunnel boring machines and these sounds. Specifically when TBMs breakthrough the end of tunnel. I've watched a load of videos of these breakthroughs and they don't seem particularly loud, i.e. none of the work crews appear to be wearing any ear pro.

I was wondering if anyone recalls this video making the connection and if it sheds any light on this theory. Perhaps it depends on the rock composition etc. I don't know.

Recently at 5 PM today, i've heard a weird metallic droning noise that didn't sound normal. I'm used to Airplane noises over my area but the past few years ever since the Hoaxdemic, I haven't heard a single plane noise over my area.

This isn't the first time I have heard something weird, it happened back in September or in August when I heard the same loud metallic droning noise. I knew something was happening behind the scenes, likely they were testing HAARP machinery or anything really.

It's very odd that I've heard an unnatural droning noise like that. Maybe they were planning something bigger?
