I don't know anymore the exact date of my sighting, but it must be between the 8th and 11th of January 2011 in the night. I stayed near Las Terrenas/ Samana in a hotel and was sitting on the balcony.I looked to the nice little mountains in front of our balcony. Suddently the two rectangular, grey/silver shaped objects in the sky came from the south and they flew fast, perfect side by side, but both with the same steady speed, with no noise in a northerly direction. They look two dimensional, like two big sheets of paper. That looked very unreal, because such an perfectly side by side flight, you can only see in movies with computer animation. I lost the sighting after the objects were passing our hotel, because i could look in the south direction, but not to the north.A short moment before there was a plane flying from north to a southerly direction with position lights. The plane was in a high in altitude and was against the two objects, only a small point in the sky. Maybe the pilots saw the same, I don't know.I couldn't believe that there wasn't clouds in the sky. I don't know what it could be. That's all I could say.
