Me and my 2 friends were hanging around when we heard a strange noise. We didn't know where it came from, at first we thought it came from an aircraft, but we realized, the airport is closed. Then we saw a flushed light over ourselves, flying in direction to the hill Pohorje. There were 3 strange triangle object with 3 bright blue lights on the corners of the crafts. Suddenly they disappeard very fast behind the hill.((NUFORC Note: We will attempt to obtain corroborating reports from the other students. PD))
