Who knows... but it is more likely that there is another explanation other than extra-terrestrial flying machines.
This one was meant to look fake, but others have been designed to fool people. Your perception of the distance that an object is from you is mostly based on assumptions made by your brain that can be way, way off. Your perception of size and speed therefore cannot be trusted.
We are not idiots. No mistake. We know exactly what we saw.
My first thought was " what's the goodyear blimp doing way out here. Then it was obvious I could not explain what it was. If it was fake then it was well done, best way I could attempt to describe it would be five jumbotron screens attached in a line inside a clear glass pill shaped dirigible, large enough and at such an altitude as to catch some sunlight over the horizon
I got good video with my cell phone, and was all excited to share it, but when I went to watch it again it started to play and then erased itself from my phone.
before this happened I thought UFO's were BS
