a strange but non frigtening evet

While on a backyard campout myself & two copmanions where watching the Big   dipper for approx 10-15 mins.  When one of the stars started to move very slowly toward the east.  Years later as a Security Policeman in the USAF I learned that spy sats. fly generally north-south. We were all straight & sober none of us ever did dope or beer. Skies were clear with no obstructions. We entered my friends house to check local paper astronomy section for possible sat. reports none indicated.
Date is approximate.  PD
