Glowing red/ green ball bouncing around the sky in non human speeds and maneuvers for 15 min , truly incredible never will forgetThe craft was circle in shape and bright red glowing ball when it was flying around for the first ten min it was red with a touch of neon green at the tip it was a perfect circle no beacon lights and no noise or sound what so ever at first I thought was helicopter because it was sitting still in the sky for sec to minutes before flying off in all directions it flew across the sky in seconds for the miles it flew but always retuned to were it started then when hovering straight back down it changed size to smaller and sold green the red color went away it also flew half way to our direction before zipping back to its original starting point after the 15 min it hid itself behind a 180 ft tree top and by then we were tired of waiting for it to fly off once again the craziest thing that this Ufo done was its turns it was flying so fast stopping at a dead hault then change its position and pattern erratically I was in the military and was in an airborne chopper unit in the 101st airborne and no man made aircraft can maneuver the way this ball of light did.
