It was a white light floating over the river, then zooming towards the water at a high speed, only to float back up in the air.at first i thought i saw a large mylar balloon in the sky, the way this object was sort of floating, i think it seemed silver in color, but bright, i thought the setting sun was reflecting on the silver surface of the balloon. ... that was my first thought. but soon i realized that the object was far away, and it was too large to be a balloon at that distance (not a manned balloon, we dont have those here). so i started watching this shining thing floating in the sky. it was in the area above our steel mill for about 10 minutes. it then sort of floated towards the river, international bridge and the soo canal locks.i found it strange, and kept watching it, but i still did not think it THAT unusual yet. i was on a hill in a large clearing and about 2 -3 miles from the locks where i was observing this. i was out walking my dog, it was later in the evening and there was nobody else out at the area. i couldnt come up with any explanation to myself as i was watching this object of what it could possibly be, so i kept on watching it.the evening became more twlight(sp?), and the object was a light on the horizon. it was the size of a large star, and was the same brightness, but it was floating (the way a butterfly flies and floats along) and it was below the level of the bridge. it floated up into the sky a bit then suddenly dropped or zoomed down at a very high speed. not strait down, but on an angle like this: / . my first thought was that it was some sort of missle going to blow up the locks. ( it was not a year since 9/11, and there had been talk that our locks could be a target). anyway, it started floating up again. it took about a minute or two to jerkily float upwards and then zoom back down toward the water. this repeated many times, and continued for about 15 - 20 minutes. i dont remember it disappearing, it just sort of vanished. it was extremely unusual.i did not report this at the time because i did not know of this site. i actually thought there would be others who had seen this and there would be a report in the news or paper about it, and i would come forward and confirm it at that time as well. but nothing was ever said and my husband thought i was 'nuts'. but i cannot forget this, it was very strange, and nothing that i can explain. i also thought i may find something in this site about someone else who had seen this. i am not sure of the date. i do know it was early summer of 2002, in the mid to late evening.((NUFORC Note: Date is approximate.
