I saw a triangular ufo while I was at work at the kabul international airportI work at the airport in Kabul Afghanistan. I was talking to my mother on my cell phone around midnight on 15 April 2010. I was standing outside in the middle of the infield next to the Radar site. I saw a dark triangular craft floating about 60-80 yards away and about 100 feet above the ground. It was dark and had even darker round type windows, it floated silently and hovered around in an area about 200 feet. I thought at the time that it was a possible unmanned aerial vehicle since the military lives just the other side of the fence. However, since I was in the Air Force and worked around UAV's for 8 years and the fact that they would not be operating UAV's on or around an active civillian runway, I can only speculate as to what it was.
