MONMOUTH, NJ, PROVIDED FOLLOWING REPORT OF UNCONVENTIONAL AIRCRAFT OBSERVED BY RADAR AT ABOVE AMY INSTALLATION. QUOTE ON SEPT. TEN, FIFTYONE, AN AN/MPG DASH ONE RADAR SET PICKED UP A FAST MOVING LOW FLYING TARGET, EXACT ALTITUDE UNDETERMINED AT APPROXIMATELY ELEVEN TEN A.M., SOUTHEAST OF FT. MONMOUTH AT A RANGE OF ABOUT TWELVE THOUSAND YARDS. THE TARGET APPEARED TO APPROXIMATELY FOLLOW THE COAST LINE, CHANGING ITS RANGE ONLY SLIGHTLY BUT CHANGING ITS AZIMUTH RAPIDLY. THE RADAR SET WAS SWITCHED TO FULL AIDED AZIMUTH TRACKING WHICH NORMALLY IS FAST ENOUGH TO TRACK JET AIRCRAFT, BUT IN THIS CASE WAS TOO SLOW TO BE RESORTED TO. TARGET WAS LOST IN THE N.E. AT A RANGE OF ABOUT FOURTEEN THOUSAND YARDS. THIS TARGET ALSO PRESENTED AN UNUSUALLY STRONG RETURN FOR AIRCRAFT BEING COMPARABLE IN STRENGTH TO THAT USUALLY RECEIVED FROM A COASTAL SHIP. THE OPERATOR INITIALLY IDENTIFIED TARGET AS A SHIP AND THEN REALIZED THAT IT COULD NOT BE A SHIP AFTER HE OBSERVED ITS EXTREME SPEED.
