Yes I remember that old TRACON game also, which I believe goes as far back as the late 80's in fact. I believe it was made by Thalion.
I've played London Control which seems OK. The only thing I liked on the iPhone or iPad was
Airport Madness. Flight Control and ATC both seemed too toyish with dragging everywhere.
I'm still looking for a good Vectoring game and a good tower game, if they exist. Also, I did another search for news about a new FlightSim but not much luck there either!
