I have seen UFO-s twice.<p>First time in early 1990ies, second time it was about 10 years ago.<p>First sight looked like a formation of lights that moved in sync across the night sky in a straight line. The formation was long, like a long rectangle or long cylinder made of stars. Not too many stars, maybe a hundred. Moving slowly straight in the direction of it's length. I could not tell how far it was, so I can't really judge for the size of it, but it was "flying" higher than the peak of the nearby mountain (which is 1km high and about 10km away), and the lenght was comparable to 1/2 of the south-west ridge of that mountain which itself is aprox. 5-6km long. So the UFO would have to be at least 1km long if it was closer, but it could be many km long if it was further. My family members saw it, as we were on the balcony at home and had clear unobstructed view. I might exagerate about the size of it, but I really did saw it. It could be easily recorded if someone had a videocamera, but we did not. We always had a photo camera at that period but nobody thought about the possibility of taking a picture. We could have tried if we had film, but I don't remember why we did not try. We didn't even talk about the possibility. When you see something like it, it does not occur to you that you might need proof and that nobody will believe. But I don't care, since I saw what I saw. Of course there can be millions of explanations what it was, but there weren't any gived and nobody else mentioned seeing it when we asked around the next day. It could have easily been a formation of airplanes.<p>The other sight, was when I was by the nearby river with my partner, who did not see the UFO. It was a regular summer night, and something flew across the sky, at extreme velocity, just like a meteorite does. But suddenly right before going out of sight, it changed direction nearly 90 degrees and continued with the same high velocity. It all happened in a blink of an eye, of course it would be very hard to have it recorded.<p>The point of my stories is that you don't always have a chance to make a recording when you see something strange.
