I do believe that these photos have ploughed through several times but sometimes a refresh can bring interest and something new may pop up.
Before I jump into what I want to jump into, I want to respond to this statement you made a little bit ago. You have made similar statements before, which taken altogether, kind of sound like you are exhausted with people going over the same old territory again and again. I want you to be okay with this process, since this is how advances are made. You get to a dead end, and you patiently start at the beginning and go over everything again. With all the people reading this forum and studying the documents, who knows what will happen if we stay open to all possibilities and new ideas.
Okay, regarding the photos -- you mention that the 3 Heads photo was actually created from a brightening of Krivonischenko's frame 34, the famous descending meteor-like thing:

So I loaded frame 34 into Photoshop, and tried several different methods until finally the "heads" showed up, through a combination of levels, brightening, and contrast:

I still don't think those bumps are sprockets. If they were, where are the rest of them? And they are not evenly spaced, as sprockets would always be.
But more interesting than that is -- now, this photo appears to show the same bright orb as the others photos, with what Teddy calls a "dead tree trunk" beneath it, except said tree trunk is now 90 degrees sideways. This means that the camera-person turned the camera 90 degrees counter-clockwise. This puts the heads, or sprockets, along the left side. I guess that means they aren't heads. Do you agree?
