Cloaked V-shaped UFO leaving a mountain in Sweden

The next video taken by a drone in June 2019 shows a possible cloaked UFO leaving a mountain in Sweden.


Drone owner:
I caught something strange when filming with my drone in the Swedish mountains.
Take a look at the video where I have pointed out some details I have noticed.


Could this really be an alien UFO sighting or maybe it´s some other craft or just some weird weather phenomenon?
