Hello, my name is d and i saw a ufo, i worked for lockheed martin and lived and worked at the kabul afghanistan international airport (kaia) in kabul. i provided radar support for the atc systems here. i am also an 8 year veteran of the usaf and worked as a barrier maint. technician on the flightline at misawa ab japan and raf lakenheath uk. i worked in close proximity with f16's and various other fighter aircraft. i was also in the 48th intelligence sq. at beale afb, ca and held a top secret-sci clearance. i state these things simply to give credence to my story. last april while on duty here in kabul, i was outside at approximately 0100hrs talking on my cellphone to my mother in texas. i was pacing back and forth in the middle of our compound, which is located in the infield of the airport, between the control tower and the active runway. i saw a matte black triangle/wedge shaped object hovering around 200-300 feet in the air above me. it was about 100 yards in front of me between the taxiway and the active runway. it had no lights whatsoever and made no sound and had several portholes in the sides of the craft. it was flat black and the portholes were completely black. it floated around in a n,s,e,w pattern for about 30-45 seconds, then descended down to about 50 feet off the ground and about 50 yards in front of me. i was explaining what i was seeing to my mother on the phone while this was happening. it looked to be about the size of a large car/suv or something of that size, possibly a bit larger. it turned around and i could see it was more shaped like a wedge than a triangle. it had ridges in it as well, like it was made from flat black and matte black materials, it then began to rise up slowly as if floating and rose up until it was no longer in view. we share our airfield with usa/nato military, i have worked with uav's before and never seen anything this big or this quiet before. plus they would never allow any gov aircraft to maneuver so close (50 yards) to an active commercial flight line. so, i just wanted to let someone know. i asked atc if they had anything on radar and they said that they didn't see anything. i contacted mufon shortly after this initial sighting and received a cursory email, no follow ups, that's why i'm submitting it on here now, i know what i saw and i would like to find out more. thank you.
