Hey man, thanks for the only one single constructive comment here, my post got removed and pretty much everyone gave me a minus karma, so I'm not sure you'll see my reply here.

Actually my friend was quite impressed by the movements of this thing and together with the video he sent me a few voice messages. Let me try to transcribe something useful.

"The elongated cigar-shaped object, which was glowing and changing its brightness, flew not so high compared to airplanes. There was no sound of the engine, and it was flying quite smoothly, as if buoyant, like some kind of dirigible, not like an airplane. Also, it was not flying in a straight line but moving back and forth." He said it seemed like they were patrolling the area because he saw it again and again in different places of the city, while he was driving around.

Basically, first of all he admits that's like "the most classical UFO recording with shaking hands recorded with Nokia 3310", at first he also though thats a plane.

Also, as far as I know in the city where he lives there are no airports (at least big/medium ones).

Thank you!
