I was sitting at the balcony of my room of the hotel and checked my photos of the day.It was a strange noice like a infra-sound. Suddenly two objects came from the sea level and went first into straight and than into not reproducible flight curves. I made a photo, pressed the camera against the balcony.The objects left many dark "dust" (because the full moon was right of the objects it was partly covered with this black dust), it last hours for elimination of the black dust by the atmosphere.The objects goes after some minutes into the sky as red stars . My camera was not working after the first photograph.The red stars was to be seen for minimum half an hour at the sky.At midnight the black dust vanished and the objects were not to be seen any more.
