So ..it happened to me last 11th of august around 00.30. I was home as that loud noise started resonating from the sky, and made me suddenly feel like going out on my terrace to have a little "check about what was that noise and what was going on in the night sky. It was quite similar to an helicopter noise, but much louder , and i quickly realized there was something totally unusual cause the noise wasn't stopping and was irregular : like becoming louder or softer in a very short time interval, meaning the "thing" i was hearing , flying in the sky , wasn't moving like any other "normal " aircraft, or helicopter that should be …Totally freaky ... .. i still can't believe this happened and that i was the only one checking it , cause it wasn't discrete at all ! so then, observing deeply the darkness of the sky, i saw some lights ( one red and the other one white , and i could see some blue/green one too sometimes , whyle moving, the white one was disappearing and i could just see a red one, like a red point. …I think i saw two of them, that were close enough; they were flying fast by doing large circles , the ones from the lights i recorded on the video . That was lasting a long time , i finally reached on taking a couple of pictures and recording few videos too . It was very difficult to catch theses lights cause as i said already before, they were moving really fast . then i tried to calm down a bit , but i was in fact totally in choc … i closed every windows and the terrace door, and tried to go an sleep , but i could still hear that noise i think until more than 2 o.clock in the morning … And that's it !
