UFO sightings in sky over Denver

[petrus4]

Petrus4 nice reply care to guess on there size? i can't get my head round them? they look cola
can size to me and maybe it is just rubbish blowing about but the "jet" like thrust is interesting.

I have no idea as to the size.  I don't think they're rubbish, though.  Rubbish to me doesn't have either that strongly directed a trajectory, and I've also never seen or heard of rubbish moving that fast.

Like I said, I don't think they're ET; but they are weird.
