Black silent hight speed triangle.I was watching the sky at night expecting some falling stars, when I saw for a second, with no noise at all, a fully black triangle, passing by at very high speed, at more or less 200 meters high. I only had the opportunity to see it because as I was watching. It emitted a brief two spots flashlights. It couldn’t have been a regular plane, as regular planes have constant blue/red lights, and they make noise!!! I looked in the direction the object was flying but didn’t notice any other light coming from it. Again, I only saw it for a glimpse of an eye, but I’m sure of what I’ve seen!
