Pull up a map of YXE and look at the flights nearby. NE of YXE is a flight with ESTIMATED in the hovered text. It indicates AFR8599 B77W SFO CDG. If you click on it, you get what appears to be the actual data, a flight going to Guatemala. Is there a bug causing this anomalous display? It seems like an extant current flight with live data should purge this estimated data.
Edit: Looks like maybe the previous entry never ended. Perhaps the flight number got reassigned or something?
