Few minutes ago, I flew a C750 from Sint Maarten to Los Angeles in Expert Server. When I was on approach at LAX, I got lucky that the Air Force One was right behind me on final to 7R. But since I am a small aircraft with slow Vapp, our separation got so tight that ATC decided to issue a go-around to the poor Air Force One. But oof, someone just disappeared on the map. Did he quit? got ghosted? It remains a mystery. Check the photos below.
