Non noise, no reflection, cylindar object

Was practicing running at football field at Henderson Junior High. observed over Rock Creek an object about 1000 feet above ground slowly taking shape. It was not fling into eyesight but like it was materalizing. There was no noise or lights upon this object and it did not reflect sunlight. there as three cyliner tubes about 400 feet each joined by same but smaller in diameter. There were no lights, window type opening or sound from object. I observed for 3 minutes and then ran home to have my daddy bring 8 MM camera to captuer object on film. it was about 10 minutes by the time we both arrived to film. Object was gone. There were no reported sightings around neighborhood as well as Little Rock Airforce base said there were no object seen on radar.
