Ive been dropping bombs in eastern Afghanistan providing CAS to troops or an outpost in contact with the enemy on the ground both day and night, and have been capped in altitude by the AWACS due to airliner traffic passing overhead east/westbound out of Pakistan.
Weird when I had a chance to later think about it.
Do those AWACS broadcast VHF sometimes?
I was over Afghanistan crossing into Pakistan airspace, blacker than a bulls tookis at night, and I'd hear "(unintelligible) cleared in tactical" every so often, it might have been over guard or air-to-air, I can't remember.
