UFO near Assenovgrad - Bulgaria

Thank you for creating this site. The incident happened some ten years ago, but probably you will be interested.
I was a soldier in the Bulgarian army. I had a duty between 2:00 and 4:00 in the morning. Those days I hadn't a swatch on me, that's why I often used to check the time looking at the stars. This time I saw a light, which was moving with random speed, changing its direction rather chaotic. First thought was that this should be a helicopter from the near airbase, but helicopters do not move like that, and do not have this type of light. I would say that the object was looking like a bright star, which was probably not so far from us. It moved sometimes slow, sometimes faster, and traectory was not straight, but rather chaotic. I actualy have some idea where this object exactly was, but I am no sure if I can say that in the Internet. At 4 o'clock my colleague came to change me. With him there were three more people. Later on he said that after about 15 more minutes, the object suddenly disappeared: 'It was like a falling star - not falling on the ground, but falling in the sky.' I would add that there was no sound, no flashes, no color changes.
Date is approximate.  PD
