With regard to the Q - 0 AF1 flight. I noted an AZAZ0909 flight on 5th December that had a zero changed to a O in it's call sign, i.e. AZAZ09O9. When I looked into it's flight history, one of the '9's was also missing from it's call sign in the history.
It wasn't thought to be notable at the time, but I knew that we were being signalled to.
I believe that it was the flight from Phoenix that flew over Cheney, WA.
