I recently added a KC-135 to FSX. It included a flight plan file called Traffic_KSAN_KLAS_KSAN.bgl ..instructions stated to but this file into FSX/SCENERY/WORLD/SCENERY folder..then at different set times i could see it take off from KSAN to KLAS and simulate aerial refueling. I loaded up the F18 and headed to KSAN at 18:00 GMT as stated in the instructions...but the KC-135 never showed up. Am I missing anything? Have traffic set to 50% for both civilian and commercial.
