PART TWO MY 1720202. PARA 11. JAMES D DIR CC CREW> REMARKS: THIS OBSERVANCE OF ATRACI< ON RADAR COULD BE cREDlTED TO INTERNAL INTERFERENCE! HOWEVER, AT THE TIME OF THE SIGHTING, THE RADAR MAINT PERS INFORMED US THERE WAS NO INTERNAL ~ INTERFERENCE ON OUR RADAR EQUIP. ALTHOUGH THE SPEED OF THE TRACK ' CKG81KG) WAS ESTIMATED AT 3 000 KNOTS, THE CALCULATED SPEED TAKEN F.ROM THE ENTIRE TRACK PATH INDICATED THE TRACK SPEED TO BE 1415 ~ KNOTS. BELIEVE THIS TRACK COULD POSSI BLE HAVE BEEN A TEST ACFT FROM MUROC OR ED~JARDS AFB. EDt!ARDS AFB, HOviEVER, COULD NOT CONFIRM THIS TRACK WITH ANY OF THEIR ACTF. OBJECT APPEARED TO BE USING RADIO AIDSI BLYTHE, THERMAL, DAGGET, AND POSSIBLE INYOKERN RADIOS. CBJECT DID NOT RESEMBLE ANY PREVIOUSLY KNOt-IN INTERFERANCE I NCURRED .
