single satellite type object omits other object flies in formation and rejoins

While camping in the desert one Saturday mid june 1976 around 2200 me and two friends were laying on a large boulder gazing upon the night sky when we observed a satellite type object traveling east to west at about 80 degrees looking north.                                     object appeared to be at a altitude and speed of a typical satellite and also appeared to be reflecting sun light. The object at about one olock emitted a twin object which  flew in a side by side formation rejoined at 12 o'clock parted again and returned to a single object at 10 o'clock. All three of us were stunned and I could not beleive a jet could fly that high and fast. I was on active duty with the  U.S. Marines and have some knowledge of aerospace and have observed many types of aircraft, weather balloons, space vehicles (Mir, Shuttle and many satellites}. I also have a interest in astronomy and have seen my share of meteors. me and my friends still talk about that sighting till this day.
