Narrative:

We were conducting skydiving operations at dillingham army airfield. On the second jump run of the morning, a military aircraft (call sign Y) reported (on 123.0) that he was transitioning to wheeler army airfield (to the southeast of hdh). He reported when he was several mi away. During this time, we informed hdh traffic on 123.0 CTAF that we were about to drop skydivers (ie, 5 mins, 1 min, jumpers away radio calls). There was no response from anyone. The jumpers began to exit the king air. 1/2 way through the load, the jump master stopped the jumpers. He saw the military aircraft (heavy) pass below us. The military aircraft should have transitioned further east but elected to cut across the drop zone. When queried, aircraft Y said they thought the drop zone was inactive, they did not hear our calls as they were talking on other frequencys while flying in our area. I confirmed on the radio with other aircraft that everyone in the area had heard my radio calls. Aircraft Y was the sole exception.

Narrative: WE WERE CONDUCTING SKYDIVING OPS AT DILLINGHAM ARMY AIRFIELD. ON THE SECOND JUMP RUN OF THE MORNING, A MIL ACFT (CALL SIGN Y) RPTED (ON 123.0) THAT HE WAS TRANSITIONING TO WHEELER ARMY AIRFIELD (TO THE SE OF HDH). HE RPTED WHEN HE WAS SEVERAL MI AWAY. DURING THIS TIME, WE INFORMED HDH TFC ON 123.0 CTAF THAT WE WERE ABOUT TO DROP SKYDIVERS (IE, 5 MINS, 1 MIN, JUMPERS AWAY RADIO CALLS). THERE WAS NO RESPONSE FROM ANYONE. THE JUMPERS BEGAN TO EXIT THE KING AIR. 1/2 WAY THROUGH THE LOAD, THE JUMP MASTER STOPPED THE JUMPERS. HE SAW THE MIL ACFT (HVY) PASS BELOW US.
