January 16 2013 – Calgary, Canada. This is very good record of the roaring noise being heard around the globe within the last 2 weeks. Metalic, reverberating as if a plane was flying by. The recorder however does not give any hint about its possible origin. The weird noises were started at around 12:30 PM and were caught on tape at 1:00 PM. Temperature was 37F and the wind speed: 7 MPH.
