I noticed the same thing. Check out the vids on the "Rods" site posted earlier in the thread. Once it has downloaded drag the progression bar slowly back and forth (slow mo effect). A couple of them look like probable insects; but a couple clearly go behind the contrail.
Yes, I see what you mean. Thanks for pointing me to that link. I don't know how I missed it the first time around.
"...if I find anything else out about this "ufo" I'll will ping you."
Thanks! I don't know what to make of this, but will definately keep an open mind.
