I installed the FS2004 'yellowknife_cyzf_2010.zip' in FSX and it works well. Excellent scenery.

Custom scenery objects include the terminal/tower, 440 Squadron, First Air and Buffalo hangers. However, for the scenery to be complete, you'll have to download/install several FS2004 addon object libraries, if you don't already have them. The author has included a list of required libraries with active links to the library downloads.

At that time [1909] the chief engineer was almost always the chief test pilot as well. That had the fortunate result of eliminating poor engineering early in aviation.
