bright light cruses through canadaon the 14th of july a bright object / light moved across the sky slowly.it would by all means appear as a star , and at a extreem distace.It was between 3AM-4am and it was quiet.The light traveled south to north.This would be the route the air lines would take from buffalo NY to montreal canada.One problem, what you see you can hear, i could not hear a plane, but this bright light stood out like a star.But then again i have seen a plane and heard a no sound.But this plane was way up there...You know when the 747's are at thier highesr altitude and seem to be a speck in the sky with a streamer behind it.You can't hear these plane.but it would have to be a huge ball of fire to be seen at this distance because i don't think we would be able to see these planes at night even if it was a clear night.we wouldn't even catch the lights of the planes at that height....I really don't know what this was but mabe i may have given something to help others in their study and if this was not a plane...i say.....BINGO......the most diappointing thing is .....I'll really never no the truth......i have out ruled many objects in the sky at night,,,including BIRDS {dulish white and fast}. But this is the one that I'll never forget....
