Turns were precise they were not gradual. Witnessed by several people who were all watching the night sky.((NUFORC Note: Anonymous report. However, we have received many such reports of satellites allegedly making abrupt changes of course. Many of those reports may be cases of mistaken identity, but we suspect not all of them are. PD))
