Narrative:
An light transport with call sign X was on a training mission. Our route of flight from vad was radar vectors direct tlh direct. Our destination was ultimately W-470 D/east and nova airspace. At FL270, ZJX approved our transponder to standby for our mission, then just south of tlh VOR terminated radar service. After entering W-470, we climbed to FL280 while talking to range control. Our mission profile called for us to cross an airway en route to our ip. We did not receive TA's from range control or ZJX on guard frequency. We were unaware that ZJX had to descend an airliner, which we had a visual on, that was at our altitude. We were operating in VMC conditions. In the future, we will contact ARTCC before exiting special use airspace regardless of what our clearance is understood to be.

Title: AN LTT PLT UNDER CONTRACT TO THE MIL CAUSED AN ACR TO DSND OUT OF THE WAY AS THE LTT WAS NO LONGER USED ARTCC CTL.
Narrative: AN LTT WITH CALL SIGN X WAS ON A TRAINING MISSION. OUR RTE OF FLT FROM VAD WAS RADAR VECTORS DIRECT TLH DIRECT. OUR DEST WAS ULTIMATELY W-470 D/E AND NOVA AIRSPACE. AT FL270, ZJX APPROVED OUR XPONDER TO STANDBY FOR OUR MISSION, THEN JUST S OF TLH VOR TERMINATED RADAR SVC. AFTER ENTERING W-470, WE CLBED TO FL280 WHILE TALKING TO RANGE CTL. OUR MISSION PROFILE CALLED FOR US TO CROSS AN AIRWAY ENRTE TO OUR IP. WE DID NOT RECEIVE TA'S FROM RANGE CTL OR ZJX ON GUARD FREQ. WE WERE UNAWARE THAT ZJX HAD TO DSND AN AIRLINER, WHICH WE HAD A VISUAL ON, THAT WAS AT OUR ALT. WE WERE OPERATING IN VMC CONDITIONS. IN THE FUTURE, WE WILL CONTACT ARTCC BEFORE EXITING SPECIAL USE AIRSPACE REGARDLESS OF WHAT OUR CLRNC IS UNDERSTOOD TO BE.
