no sound or lights

Ok i was doing some jogging as a young kid and seen what was like unto a tv tower three legs being a cylinder shape about 100 feet diameter each conected by a cross beam type frame. Ship did not produce any lights or sounds and appeared as if slowly from nothing to the full view and was gray like in color. it maintained a position above football field where i was practicing my jogging. it slowly disappeared as it had appeared with no sound or movement  Has anyone seen such type ships and where do i locate such stories. This was a real ship and i've seen lights in the distance and such but this was a real ship and i am now trying to find other stories such as mine. Thanks
