Narrative:
As I was taxiing for departure, 2 fgt called 10 mi final for opposite direction arrival. The first aircraft landed and engaged the barrier, thus becoming entangled in the cable. The second fgt called a 6 mi final. I called taxiing out behind the entangled fgt and would be departing opposite the arriving jet and would make a turn side-stepping to the north. On departure the perceived time between jets was dramatically shortened. After rolling out of the clearing turn the inbound jet was retracting gear and executing a go around. As the jet on the runway was still caught in the cable, the second jet could not have landed. However it is unknown whether my hasty departure caused the missed approach or the jet was executing standard procedure for their operation. Secondly, the status of military and civilian operations at a closed military base leads to confusion of priority and the requirements for military procedures versus civilian (i.e., was it proper to take the runway while a military fighter was being disengaged from the barrier by the ground crew, was it proper to depart opposite an arriving jet (what are their separation/arrival requirements). Note: at no time was there a near miss situation. Aircraft separation was adequate.

Title: NMAC BTWN AN SMT ATX AND A MIL FGT NEAR THE RWY ON AN UNCTLED ARPT.
Narrative: AS I WAS TAXIING FOR DEP, 2 FGT CALLED 10 MI FINAL FOR OPPOSITE DIRECTION ARR. THE FIRST ACFT LANDED AND ENGAGED THE BARRIER, THUS BECOMING ENTANGLED IN THE CABLE. THE SECOND FGT CALLED A 6 MI FINAL. I CALLED TAXIING OUT BEHIND THE ENTANGLED FGT AND WOULD BE DEPARTING OPPOSITE THE ARRIVING JET AND WOULD MAKE A TURN SIDE-STEPPING TO THE N. ON DEP THE PERCEIVED TIME BTWN JETS WAS DRAMATICALLY SHORTENED. AFTER ROLLING OUT OF THE CLRING TURN THE INBOUND JET WAS RETRACTING GEAR AND EXECUTING A GAR. AS THE JET ON THE RWY WAS STILL CAUGHT IN THE CABLE, THE SECOND JET COULD NOT HAVE LANDED. HOWEVER IT IS UNKNOWN WHETHER MY HASTY DEP CAUSED THE MISSED APCH OR THE JET WAS EXECUTING STANDARD PROC FOR THEIR OP. SECONDLY, THE STATUS OF MIL AND CIVILIAN OPS AT A CLOSED MIL BASE LEADS TO CONFUSION OF PRIORITY AND THE REQUIREMENTS FOR MIL PROCS VERSUS CIVILIAN (I.E., WAS IT PROPER TO TAKE THE RWY WHILE A MIL FIGHTER WAS BEING DISENGAGED FROM THE BARRIER BY THE GND CREW, WAS IT PROPER TO DEPART OPPOSITE AN ARRIVING JET (WHAT ARE THEIR SEPARATION/ARR REQUIREMENTS). NOTE: AT NO TIME WAS THERE A NEAR MISS SIT. ACFT SEPARATION WAS ADEQUATE.
