Narrative

AT APPROX XA50; ACFT #1 CALLED DEPARTING FROM A SATELLITE ARPT APPROX 8 MI SW OF THE PRIMARY ARPT. I INSTRUCTED THE PLT TO MAKE STRAIGHT-IN APCH TO RWY 1. 2 F16'S WERE APPROX 10 MI ON FINAL TO INTERSECTING RWY 33; MAKING AN IN-TRAIL ILS-DME APCH (APPROX 2 MI BTWN FLT ELEMENTS). THE F16'S WERE CLRED FOR OPTION. IN THE MEANTIME; I HAD NOTED ACFT #1 ARTS ACQUIRE IN THE VICINITY OF THE PRIMARY ARPT AND ESTIMATED 5 MINS UNTIL THE ACFT ARRIVED AT THE PRIMARY ARPT. I PERFORMED A COUPLE OF ADDITIONAL DUTIES; THEN OBSERVED THE FIRST F16 XING THE LNDG THRESHOLD AND THE SECOND F16 APPROX 1 1/2 MI ON FINAL. I LOOKED AT THE TWR BRITE FOR ACFT #1'S ARTS TAG AND DIDN'T OBSERVE IT. I THEN OBSERVED MOVEMENT ON RWY 1. IT WAS ACFT #1 EXECUTING A TOUCH AND GO (BTWN THE 2 F16 FLT ELEMENTS). THIS PLT WAS DOING THIS WITHOUT CLRNC. NO CORRECTIVE ACTION WAS EFFECTED BECAUSE THE OP; EVEN THOUGH RESULTING IN LOSS OF SEPARATION; WAS SAFE. SAFETY MIGHT HAVE BEEN COMPROMISED IF ACTION HAD BEEN TAKEN. THE INCIDENT WAS RPTED TO WATCH SUPVR AS REQUIRED BY FAA ORDER.
