silent vibrating disc flashes and dissappearsThursday June 23, 1;16pm – Kansas City, KS. I was driving to a Drs apt and I was headed west on Ruby Av from 14th st. after a stop sign at 14th & Ruby.In the sky, directly west, was a shiny white disc-shaped craft floating slowly from south to north.It had no lights of any color, and it looked as though it was vibrating at times (briefly).I slowed to watch the object, and had it in my sight for about 8 to ten seconds, then I went under an overpass, and I emerged just in time to see it flash very brightly two times and vanish. The object made NO sound.There were several other vehicles and pedestrians in the area, even a car in about 25ft ahead of me driving with 2 passengers, but no one else seemed to be reacting as if they saw it.It wasn’t very high in the sky: lower than most planes fly. My heart was POUNDING! – I looked for other people’s reactions, but I don’t think anyone else saw it.Great experience, though.
