UFO real? It happened three years ago, in the cold and quiet montains of colombia, not very far from bogota. We went to this place because one friend has a cottage that he use to relax. One night, three friends and I decided to go out and enjoy some snaks and drinks beside the cottage, it was a normal night, very cool and silent, also the sky was absolutly clear, you could see every star shine. We were enjoying the night, when suddenly we heard a very sharp noise, it finish after 5 seconds, so we were not worried about that. Thirty minutes later we heard the same sound and again during 5 seconds, and also we could feel a small vibration on the ground, so it was a little bit disturbing because it was not usual. 10 minutes later, we saw a unexpected light above the montain, it was like some kind of craft with a powerful light, hovering in the sky. Suddenly, this object started to move, crossed the sky at unbelievable speed and finally the object disappeared. It happend very fast, so we was not abble to take some picture or evidence.
