Walked my dog in the morning along the haydn park in vienna. when i came between two trees and looked up in the sky i saw a plane passing in the whole blue sky. then this "cigarette" appeared flying the opposite direction than the plane and definitly closer to the earth. it was a white weakly glowing cylinder without any aerodynamic support like wings. the sun stood high behind me and i realized, that there was no shadow under the "cigarette". suddenly someone from over the street called me and as i looked over i recognized a girl-friend of mine. i asked her to come over and have a look what i see. she followed my eyes and saw the "cigarette" and her first words were: a plane. i asked her about any wings and she said, there were none. so she realized, that there was an aerodynamically unrealistic flying object. the speed of the "cigarette" was that of a private plane at 500m height. and its size was about 2cm at armlength. my girl-friend took her smartphone and zoomed in to take the clip. sadly to say is, that the first zoomed in before she started recording, so there is no background to see.
