i saw that post too when I googled it. i see lots of spotters shot pics of the AF1 in Europe. lucky them. I wish i had that opportunity.
so to clarify, if it is blocked it doesn't show up at all on here? edit i think i understand that if it's blocked it doesn't show up on the other sites but ADSB still picks up available data. what I don't understand is why ADSB exchange is allowed to show military aircraft but not the other sites. I use Flight Aware for most everything else because it shows the flight schedules for commercial aircraft but it doens't show smaller aircraft as much and doesn't show military aircraft.
I hear AF1 on the live ATC radio feed for Joint Base Andrews AFB. https://www.liveatc.net/search/?icao=KADW
