Mindless UFO chatter

Over 140 frames showing two or more "craft" of unknown nature in 2:37 minutes out of 45 minutes originally recorded over a quite small region of the sky. After going over the site where the objects were recorded I had to redo my original thoughts on altitude and to a lesser degree, speed.

While I still say they are around 15-20 feet in diameter, I would put their altitude at around 3500 - 5000 feet. Given the field of view at 40x with some of the objects being almost in focus, which was set on auto. . Still, all this is irrelevant when one comes to understand the size of the "fleet" that was passing by overhead completely unnoticed by those below. I have yet to talk with anyone at the airport tower on the day in question as the objects tracked right over the local airport. How long were they passing by before I started filming? How long after I stopped? Since their tail fins? scanners? was facing down as they passed overhead was it just a survey party? I have no idea. That they were there, en mass as it were, and of a solid nature is beyond dout as far as I'm concerned and as for anyone else..oh well, whatever gets them through the day.

While I have had many other sightings this one still holds my interest more than the others because of what it may mean as I look into how better to capture these seemingly invisible craft and some day maybe their occupants.
