It's a safe bet the drone was on standby circling the area when his plane arrived. We knew what plane he was taking before he boarded. Out of courtesy for the innocent civilians, we waited until his little convoy was clear of potential collateral damage. Nice shot!
I agree. I meant that they probably had a spotter to verify the convoy. I would think that the Reaper had to stand off for some distance so it didn’t get into the airport airspace.
