FOLLOWING OBSERVATION - MADE BY DET THIS STATION. PART 1. AT APPROXIMATELY 111&2 GCT 23 FEB 'I A DISTINCT BOOM, SIMILAR TO A SONIC BOOM, WAS HEARD FOLLOWED BY A ROLLING RUMBLE LIKE DISTANT THUNDER. IN AN OTHERWISE PERFECTLY CLEAR SKY, THERE APPEARED A DNSE WHITE CLOUD WITH A LESS DINSE ZIG ZAG TAIL TRAILING AWAY TO THE SOUTH. THE TAIL INDICATED A TRACK FROM SOUTH TO NORTH. THE TAIL DISAPPEARED AFTER ABOUT Jl MINUTES THI DENSE WHITE CLOUD PERSISTED FOR ABOUT 3~ MINUTEs. DURING THIS TIME IT DRI7T!D VERY SLOWLY TO T~t EAST ABOUT 15 DEGRES THE CLOUD DIAMETER SUBTENDED AN ANGLE OF ABOUT 2 DEGREES THE ELEVATION ANGLE WAS ABOUT 61 DEGREES. PART 2. THE FOLLOWING OBSERVATION VAS MADE BY A SENIOR OFFICER AT A LOCATION ~ MILEs DUE NORTH OF DKAHARN. HE HEARD THE BOOM FOLLOWED BY AN UNDULATING LOV PITCHED WHISTLE OR RUMBLE STRONGLY SUGGESTING FRACMENT! TUMBLING THROUGH THE AIR. HE ESTIMATED THE ELEVATION ANCLE OF TH MAIN CLOUD TO BE 81 TO 8' DECREES ON AN AZIMUTH HEADING OF ai DEGREES EAST OF NORTH. SECURITY CLA8SI~1Ct MESSAGE~ORM tJBCI,AASJP I tm SPACE!
