There’s just too many other pictures of contrails that extend to the ground though. It wasn’t at the ground, it was 35000 feet where we see the ‘horizon’ and the contrail intersect.
An airplane contrail *looks like* it extends to the ground because the earth is round.
Well, it was one heck of an illusion if that is the case. I have been near this military wise and it is very similar. I’ll dismiss it as nobody is saying anything but the Ruskies so that alone may be enough for me. It’s been fun playing though. :^) Dr. Falcon
