While at the beach at bald mountain recreation area, i spotted a stationary black spec. eventually the speck began moving against the wind direction below the clouds. at times, the object seemed to change shapes as if it were rotating or tumbling along all three axis. while rotating, the sunlight would reflect off the surface of the object. the object got larger, as if moving closer towards the earth. i lost soght of it after about 15 minutes when it moved over the horizon. my friend, and at least one beach gower saw the object. additionally, a low flying, single engine plane flew through the area. the plane was lower on the horizon. the black speck made no noise that i could hear.
