Strange sting like object over northern Ontario CanadaIt was a clear string that would come into focus as a distorted blue sky, it was like looking though a water fall. It was moving faster than the speed of sound, I had observed a F-18 going by at the same speed. It had no visible thickness, I would compare it the northern light. The thing was at least 300 ft in total length. This was observed on a clear day no clouds. This thing was at least 10,000 to 12,000 ft above ground. It look two dimension.
