A witness account on file, unevaluated. Most of the archive rests here, and honestly so.
The report, as filed
This perfectly spherical black object moving in a straight line high up in the sky. I managed to take a video of it. It could be nothing but the way it moved slowly across the sky in such a straight line and being so perfectly round was very bizarre [NUFORC annotation: Balloon - Possible]
Held as-reported from National UFO Reporting Center (record NUFORC #176018). Witness text is preserved verbatim, including its spelling; nothing is edited beyond formatting.
