In all fairness, the transfers at DAFB come in at night only. It’s never done during the day (I live about 10 miles from DAFB).
I wonder when they changed that because thy used to come in when they came in, day and night. In another post you mentioned the choppers from the Pentagon from 9/11, believe me, so do I. I lived less than a mile from the tarmac at DAFB and the air space silence was scary and the first airspace sounds I heard were those choppers, and they weren't at night.
