These strange noises in the sky are a good catch!
Do you know what was causing them?
January 8 2013 – ZAANDAM – KALF, Holland. The strange noises were recorded at 12:24 A.M., so this morning in the city of ZAANDAM – KALF in Holland. In the first 20 seconds of the video, only something faint is heard in the back. After something like 24 sec, the weird sounds similar to an plane flying by are strong and clearly audible. A great catch! Thank you for sharing it.
