UFO Sighting in Dallas, Texas on 1997-08-13 17:07:00 – Flew over house

I walked out my back door and there was a perfect silver sphere moving south to north of dallas. i froze in place knowing this was not a balloon or anything. i snapped out of it and ran inside to grab my cam corder. i caught it just in time as it spead rapidly to the north. i filmed as long as i could see it. i broke up with my gf at the time and she kept the footage. she made a copy i shared with a friend that refused to return it. i have their names, they might share it. to be clear this was a perfect sphere. no tear drop, nothing hanging under it. i would say it was the size of a house at least. not a balloon!
