Strange lights formation in triangular shape passing over 100 witness'sIt was Christmas evening and we were all gathered outside at the mine site to have our Chrictmas diner, when the manager notice the triangle shape object in the sky. We were all amazed as he pointed to the object and all observed for at least a minute. The object travelled not much faster than a jet airline. The lights were not flashing and no noise was heard. We wondered about it and I decided to check the web sites only to find out we our not the first to see this in the world. What is this?
