I was playing Kerbal Space Program in a sandbox world, and I was doing a simulated emergency landing flying the Aeris 3a near the mountains behind the space center. Suddenly, I saw three small lights, two at the bottom of a mountain and one on the top. I toke a screenshot and when I go to see it I saw something that I didn’t see before. There was a strange black object, with a triangular shape. I ran immediately a mission to check what the strange object was, but when I arrived near the mountains I didn’t see anything. I never saw the lights or the UTO (Unknown Triangular Object) anymore. Here the screenshot, the only proof of his existence. - - - Updated - - -
