It was in the late summer of 1976 in Tehran, Iran. I was a sophomore at Tehran American School.

Me and five of my TAS buddies went camping in the Alborz mountains.  We were laying out watching the stars late at night. The sky was very clear and the heavens were brilliant.  
One of the twinkling stars all of the sudden got much larger as if is was coming toward us. Where all the other stars looked like a pin points in the sky, this star looked like the size of a dime.  Then it stopped getting bigger and shot off in a trajectory that crossed about 1/4 of the sky, then it zigzagged around for a bit, and then it receded into the sky until we couldn't see it anymore.
After a couple minutes one of my friends said, "Did anybody else just see that?"  We all had.  It was a bright round light in the sky but I have never seen anything move like that before or since.  
Around that same time, there was a UFO incident reported in the local newspaper.  My father worked at! Mehrabad airport and I remember him joking about it, though he didn't believe it, and he wrote my story of that night off to satellite reflections in the sky.

Aloha Peter,
I’m sorry, I missed that radio program.  I think you received the two reports because an old classmate of mine sent me your link after filing one and then asking me if I wanted to contribute.  Our experiences were different but I believe it was the same event or around that same time.  My father was a military contractor with the Iranian Air Force back then, and it was all the talk among his cohorts.  Dad was very much an unbeliever and wrote it all off to atmospheric conditions and the pilots' active imaginations.  I don’t go along with that, as from my point of view, the night was very clear, and I saw what I saw.  For me it was exactly what it was, an Unidentified Flying Object - no more, no less.
