Thanks Robin. I know that you still are one of the very few GW aficionados. You already said that on other sites.
One of the main problem with GWE is the fact, that default GW traffic and some others use default airports. Let f.i.flying a DC-3 from Paris Charles de Gaulle to Hong Kong Chek Lap Kok is an absolute nonsens. Also I don't want to have all the modern airports in my GW world. Therefore I deleted all AB9xxxxx.bgl and AP9xxxxx.bgl files as well as the object files (OB9xxxxx.bgl).Regrettably I now miss all famous buildings like the Empire State, Buckingham Palace or Eiffel tower.That's the price.
So finally I'm struggling with recreate basic airfields to allow the get the other GW traffic mostly included in scenery packages to run in a vintage environment.
Needless to say that creating historic flights like those done by Alan Cobham, Chichester or Douglas World Cruiser will be a tremendous work. But at least it's fascinating to search, know and understand how the world was in the Thirties.
