I idownloaded here the "Fs2004 - Tinian 1945" scenery package. To complete AI traffic, following aircraft should be added according to the author:
You have also to download following aircraft (F4U Corsair) and repaints (a part are for CFS2, but work without problem in FS2004), from www.flightsim.com : corsair6.zip (you can keep it to fly, it’s an excellent aircraft!)
But once again, it's still impossible to search this particular file. I'm not going to download every F4U and/or Corsair entries here, in order to get eventually a chance to found the correct file. After numerous months it's still impossible to handle correctly and userfriendly the FlightSim.com library. It's by the way an outrage to the contributors which did the reputation of this site for many years!
