I finished watching a world cup football match on tv, in an open beer garden call brlo, near the gleisdreieck station. as the match finished, we went with 2 friends to the field next to the brewery, and were talking. at some point i saw something in the sky with the corner of my eye, when i looked in the sky there was a big triangle/teardrop shaped, silver ufo hovering over us. it was just standing there one second, and the next second disappearing into the horizon leaving a bright line behind. the bright line disappeared almost immediately. i didn't even had time to tell my friends, as when i told them, it was all gone. i was shocked and surprised at first, but then i felt good, because i always wondered if it was real. now i know it is.
