I noted in another thread a comment about a flooded airport. I discovered a similar problem with TNCM and encountered additional problems. The airplane is not positioned on the end of the selected runway. There is a large hill behind Rwy 28, which is missing. I tried the Visibility (Z/z) adjustment to check if the hill was just in mist, but to no effect. And at the moment the splash screen dissolved, the plane was spinning in the air and then set down on the surface.
The Constellation presented another incorrect aircraft placement.
Several other aircraft I tested (757-200, 777-200ER, Aero Commander, A-4) loaded correctly, but the flooded airport and missing section of scenery was present in all instances.
Regards.
