This was recorded on the 22 of September 2011 over south Denver Colorado.
I was using a Redfield spotting scope at X60 times and a Casio camera in 210 frames per second video. So these objects are flying at a very high speed.
This large object (video 1) could be a possible clocked UFO huge ship right over head, it was invisible except for the edge of the craft as the Sun hit the edge. It was very hard to determine the exact size..
