Daytime disk flying in stormy Denver weatherI am in sales and have a great view of the sky outside my window. At this time, there is a storm blowing through the Denver metro area. I just walked outside to the south of my building to watch the clouds churning, looked up to the southwest, and I saw a dark circular object -- almost like a child's helium balloon -- sort of hovering and "drifting" toward the north. I was surprised at how slow it moved because the wind was pretty strong. It was at this point about 1/2 to 3/4 mile away. I watched for a few seconds and could tell it wasn't a balloon, and it went out of sight around the corner of my building, so I ran through the building to the other side and caught sight of it again. By this time it was a disk shape, more elongated, still dark in colour, and flying a bit faster toward the north. It suddenly slowed down, then wobbled and went slightly sideways, and at that point it changed to more of a white colour briefly, then it tilted back to a horizontal position and started moving again to the north. I ran inside and yelled to some CSRs (who were just 15 feet inside the door), "Come tell me if this isn't a flying saucer!" and they all 4 ran out. One of them could also see it, but the other 3 couldn't. It was flying rapidly to the north, seeming to fly faster all the time. It was still an elongated dark object. We watched it for a few seconds until it disappeared. It was moving from SW to N/NE. When I first saw it, it was probably about 1/2 to 1 mile away, and by the time the CSR saw it it was still about 1 mile away but was travelling to the west of our building, toward the north.((NUFORC Note: We express our gratitude to this MUFON member for submitting the report.
