Assuming they're real images of something in the sky I'm not sure what they'd be, the image quality is very low so that makes it pretty tricky.

And they included several images:Time: January 2nd 2:05pm
Location: Denver, CO
Statement: I was waiting in a drive through line and watching the sky. There was a plane flying above me and as I watched it pass, I noticed a tiny black dot miles above the plane at a distance. It was coming towards me and I tried to record a video first, but it was so fast and small I couldn't zoom in close enough to focus. I managed to snap these pics as soon as it came closest to me before it was flying away the opposite direction.
I am inclined to repost (was deleted because i didn't post correctly) because I just watched "Transmedium: Fastmovers and USOs" and it looks like the shape and speed of the "go fast" video they show.
