Somewhere in Poland, strange sound recorder on March 17, 2012.
The author’s comments:
Sorry for the bad quality of the movie, but I don’t have a good camera and video is not important in this. It happened in the middle of the night around 1:57 CET. The sounds lasted about 15-20min. The noise woke me up and started to recording after a while.
This is my first video on YT so please excuse the quality :).
