I talked to someone who said they heard AF1 SAY WHO THEY WERE TO atc ONCE.
What? AF1 uses that callsign anytime the prez is on board. I heard him many times when I was out flying. ATC just cannot advertise when AF1 is operating. That's why the OIS just says VIP movement whenever he comes in and stops traffic. Most pilots know how to take the hint when AF1 is in the area.
well what do they do if theres planes in a queue for takeoff, or planes in final landing sequence?
