It was a black orb
I too have seen a black orb. From a distance of less than a quarter of a mile and probably only a hundred or maybe 200 feet up. Spotted it on a lunch break outside work with 3-4 others, this back when cams on phones were awful quality. It just glided silently in a straight line, funny enough along the course of railway tracks. It would have been maybe 10-20 feet maximim in size to look as large as it did, which would rule out a balloon. My work mates laughed when I said it may be a ufo, and showed no interest at all.
But what it was, I will never know. Except it wasnt a baloon - as the wind didnt move it at all, and it maintained a perfectly straight course.
