Bright light in the sky, over a 30 km from the military machine. stationary from period of time than suddenly changing direction with several km per second i was soldier in that time. i was operator to the distance in ‘’ossa’’. i have to capture the distance from us to the military plane. i took the distance on the computer in the machine; the object was about 30 km from us. suddenly the computer lost the target. i took again the object but in a few seconds it disappeared from the display. we were 10 persons in two machines. we went out from machines and saw the bright light in the sky. there were no clouds. clear sky and sunny afternoon. we observe the object about 20 minutes. it changes his position with 10-20 km per second. it did it several times and suddenly disappeared. the same evening a general from the border defence air forces spoke on the phone with all of us –eye witnesses about the event. he told me that other soldiers from the border defence air forces have seen the same object and it was probably an ufo. he told me that this have to stay in secret.
