STANT, ANDREW J. REID, G-TWO FT. MONMOUTH, NJ, PROVIDED FOLLOWING RE-
PORT 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 UNDETER-
MINED 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 AIR-
CRAFT, 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.
SEPTEMBER TEN, FIFTYONE, AN SCR FIVE EIGHT FOUR RADAR SET AT THREE
FIFTEEN PM TRACKING A TARGET WHICH MOVED ABOUT SLOWLY IN AZIMUTH NORTH
OF FT. MONMOUTH AT A RANGE OF ABOUT FORTYTWO THOUSAND YARDS AT THE
EXTREMELY UNUSUAL ELEVATION ANGLE OF THIRTEEN HUNDRED FIFTY MILS,
APPROXIMATELY NINETYTHREE THOUSAND ALTITUDE. ON SEPTEMBER ELEVEN,
FIFTYONE, TWO SCR FIVE EIGHT FOUR RADAR SETS AT TEN FIFTY A.M. PICKED
UP THE SAME TARGET NORTHEAST OF FT. MONMOUTH AT AN ELEVATION ANGLE
