On Sunday night, August 21, 1994, at 10:35p.m., a triangle-shaped craft was observed flying over U.S. Route 23 in front of the local Dupont plant, just south of Circleville, Ohio. It was heading northeast at about 3000 feet and approximately 300-350 miles mph. It was first seen below the full moon for about 3 or 4 seconds. The whole sighting lasted about 20 seconds. These figures are of course estimated. No sound could be heard above the outside plant noise (which was moderate). The bottom of the craft was seen from the 5th floor at the plant. It looked grayish in color. The craft appeared to be a little longer than the fuselage of a Boeing 707. Two large white blinking lights were on the end. Both lights blinked at the same time. Another small red light appeared in the middle. Two small white lights were in front bottom of the braft. These lights also blinked. I was outside and looking toward the moon, which was high up in the Eastern sky. It was cloudless at the time in that section of the sky. The outline of the craft could clearly be seen because of the moonlight. The craft was last seen just east of the local GE plant and still flying horizontal. I later called Rickenbacker Air National Guard Base's control tower. No other calls were received about this sighting. My personal feeling is that this object was perhaps one of our secret projects or an alien craft.
