Non moving, soundless , tri-cylinder, object that appears and just fades back into sky

Three gray looking cylinder tubes each tube about 400 feet long connected by a cross beam type structure. There was no noise, lights, smoke or any sounds of any type of engines. The craft appeared slowly as if it was coming out of a fog bank, yet the sky was clear and blue sky was seen thru the cross beams of craft. Craft was not moving in any direction and was stationary over a football field at Henderson Jr. High. I was running track practice at the football field when I seen the object.
I ran home to get my daddy to bring his 8mm movie camera but when we returned the object was not seen. I never heard of anyone else in the area every seeing this object I seen. Is there many people who have seen such a shaped object with no sounds and no movement and seemed to slowly appear in our sky and then just disappear slowly as if fading into clear sky? Thanks for any replys.

Date may be approximate. Witness occupies a job of considerable responsibility; the report probably is quite credible, we suspect.  PD
