OK, so I'm using TTools 2.02. I compile my flightplans and get an error: "a flightplan specifies AC#58444 that aircraft is not in the aircraft.txt". So, I think, fine, we've seen that before and search my flightplans.txt for a stray aircraft that isn't numbered correctly. Odd thing is, there is no AC#58444 to be found anywhere in the flightplans.txt. What now? :-hmmm any clues appreciated.Misha
