Mysterious sounds around the world coming from the sky

Mysterious sounds have been heard booming from the sky from Europe to Canada. The unsettling noises sounding like groans and powerful horns, in some cases they were so loud they set off car alarms.

There’s been a lot of buzz over the last few weeks about strange sounds being heard in the atmosphere. People around the world and here at home have reported hearing some bizarre noises.

This is not the kind of video I usually post but thought it was strange enough to put on.

I came across another video about this on you tube. The sounds were being heard and people were wondering what they were. After close Investigation, it turned out that ther was an airport 2 miles away that was testing a new engine.
