Narrative:
Fgt X departed bgr at FL200, requesting to operate in condor MOA at 7000' B FL600. Due to traffic, military flight, was cleared to delay in condor at 7000' B FL370. Mlt Y departed bgr to brv at 8000', which traverses the condor airspace. Mlt Y requested climb to 10000' due to turbulence and was issued 10000'. I then called fgt X to condense his block 11000' B FL370. I received no response on frequency 219.6. I then asked fgt X to acknowledge clearance with an identify--no identify received. Contact attempts were also broadcast on guard frequency 243.0 with no response, verbally nor with identify. Fgt X was consistently operating in the northern portion of condor at an altitude of FL180. I assumed he would stay to the north, but he took a run at mlt Y and sep was lost (1.9 NM, 400').
Original NASA ASRS Text
Title: MLT Y HAD LESS THAN STANDARD SEPARATION FROM FGT X. SYSTEM ERROR.
Narrative: FGT X DEPARTED BGR AT FL200, REQUESTING TO OPERATE IN CONDOR MOA AT 7000' B FL600. DUE TO TFC, MIL FLT, WAS CLRED TO DELAY IN CONDOR AT 7000' B FL370. MLT Y DEPARTED BGR TO BRV AT 8000', WHICH TRAVERSES THE CONDOR AIRSPACE. MLT Y REQUESTED CLB TO 10000' DUE TO TURB AND WAS ISSUED 10000'. I THEN CALLED FGT X TO CONDENSE HIS BLOCK 11000' B FL370. I RECEIVED NO RESPONSE ON FREQ 219.6. I THEN ASKED FGT X TO ACKNOWLEDGE CLRNC WITH AN IDENT--NO IDENT RECEIVED. CONTACT ATTEMPTS WERE ALSO BROADCAST ON GUARD FREQ 243.0 WITH NO RESPONSE, VERBALLY NOR WITH IDENT. FGT X WAS CONSISTENTLY OPERATING IN THE NORTHERN PORTION OF CONDOR AT AN ALT OF FL180. I ASSUMED HE WOULD STAY TO THE N, BUT HE TOOK A RUN AT MLT Y AND SEP WAS LOST (1.9 NM, 400').
