Thanks for your response to my question. Wouldn't that be true if KPHL was downloaded as a separate scenery package? This is the default KPHL airport I'm talking about.Seems to me it should load all the time. Even when I clear my Custom Scenery folder of all downloaded scenery, I still can't go to KPHL without the error msg and then invariably, a crash to the desktop.. And for that matter, it might be more airports.
