Original unedited file for those wanting to closer inspect.

sorry, I have been out of town for a few days. To answer your earlier questions. I have seen them with out contrails several times.
Like I said in the description they seemed to swivel and move back and forth. You know how a shark swivels back and forth whilst it moves forward? Much like that although the object was solid and did not bend like a fish. When you said it was vibrating that definitely made a lot of sense and was true. On the art one I can still see antennas! There is no way these were bugs, at least not normal earthly bugs, they were bigger then any bug I have ever seen and I have lived in all kinds of tropical countries. I really have no hypothesis for these except something that sound s completely weird. I felt like these things were injured or sick maybe lost. The way they were moving and the way I felt was reactive rather then intentionally moving about in this way. Hope that makes sense.
