This siting was sometime in 1963-19653 of us were standing in front of the pool hall and heard a whoosing sound. Looked up and this large rectangular object cruzed up River St. to the lake (Superior) and continued on. It felt like some sort of static electricity was in the air, it was a clear sky & this object blotted out the stars in an area like 100' wide by couple of 100' long. It was impressive as I'm 64 now & still remember it as if that happen yesterday. The craft was dark except for two lights at front & back end on either side.
