Captured in Aalborg Denmark on January 10th this is a very strange one. Skip to 1:20 to hear it.
The person who recorded it claims it was much louder in person. They say it “sounded like it came from the heavens”. The noise lasted a few minutes which is a short duration for most sky sounds. They can’t identify the sound and stated that they’re sure it’s not an airplane, train or helicopter.
The closest thing I could find that is similar to this is the well known New Jersey video from last year (below).
Believability Scale: | | | | | | | | | |
plus: sounds genuine, person has no related posts on YT, a not super clear recording that sounds very atmospheric
minus: in a city where sounds can be anything, very short in duration
Well, you may wonder if it´s their Blue Beam project testing it´s capabilities, or it could be big spaceships from where this noise comes from. It is weird…
