I have watched this several time and I don't have a clue but I am no expert. I read about Water injection (engine) which creates the black contrails but is it used this high for this long? One of the you tube comments claims it's an old school surface to air missile fueled with solid propellant.
You can watch in 720p.
I know there are some experts out there so give me a sign man.
Over the Aegean? A Gyro.
Looks like another aircraft flying on a different heading, about 80 degrees to the photographers heading.
Not a SAM. Too slow.
When the contrail moves from left to right the video looks like it skips to me.
UFO? I guess. Alien/Extraterrestial? Um, no.
My guess. About the time the Chinese space station reentered the atmosphere.

Water injection was only used at takeoff with turbojets to keep the burner cans cooler at full power. A B-52 or KC-135 would only have about a minute's worth of water on board for injection. This would create sooty exhaust but not a black contrail...except
It was so cold at Grand Fork North Dakota one day (-40 degrees F) that I did witness a KC-135 contrailing at takeoff. I never want to be that cold again.
Solid propellants used in missiles burn with a very white or slightly yellowish plume, not black. A missile plume is also more persistent than that contrail it would be streaming from the source.
It’s another airliner, just below the local horizon after sunset at a lower altitude, making it’s contrail appear dark.
Contrail of airplane flying approx. perpendicular to airplane from which this video is taken (explains movement of contrail). It is dark, I believe because a higher altitude cloud layer is above contrail, out of view, and is blocking the sun, and casting a shadow on to the contrail, which makes it look darker. If could see below the wing, at the cloud layer far down below, would see more of the shadow.
Black contrails, huh? Well, maybe if the aliens changed their oil regularly theyd get better mileage.
“To Serve Man”.
Turkish F-4 with the old smoker engines. You could literally follow them through dense fog because of the trail they left.
It just looks like a jet contrail to me.
Looks like a jet aircraft trailing a long plume of exhaust/contrail under the right conditions to do so.
Greek Air Force still flies F-4’s, they leave black smoke.
That image looks like a B52 from behind.When those 8 engines are running they smoke like hell.
Most commercial jets have much cleaner burning engines.
A B52 flying at 90 degrees away from passenger craft?
An image of something moving at high elevation taken from something else that is moving at a high elevation. It - the suspect image - could be all sorts of things.
