Iwitnessed one object moving east to west across Rt.539 4 mile north of Rt.72 near the Fire Tower. There were no cloud and the sky was completely clear. It stoped for app.15 min. hovering about fifty yards in front of me. It was rectangler with rounded corners on bottom (app. 40'wide x 60'long)and 10' high bottom to a 6' 45 degree angle to the top which was flat.Bottom 10' section was wrapped with two three foot cylinders inside the cylinders were white lights 6' apart the top cyl. was rotatining clockwise and the bottom counter clockwise when the lights passed each other they would hume. The upper section had app. 4 foot porthole 8 to 10 ft. apart but were faintly lighted. When the UFO left it was moving at about 5 mph for 2 miles then asinded at at 60 deg. angle and was out of sight in 5 seconds. I called McGuire Air Force Tower and they said had no aircraft in the area.
