Thank you for your test & time. As I suspected, something is missing from your pc for the mission to run. I mean some element of the mission is not there. And it can be one of either : 3d ground crew, f-18 omar skin or the ufo. This is Free Flight, though you opened it from Missions Menu. Only thing I can think of, is that you have not placed 3d ground crew in Add On scenery of FSX. (I mean the contents of texture & scenery folders found in folder "3d us ground crew", inside the corresponding folders of Add On Scenery).

Okay. Although I have done all that, I shall redo it all again. At one stage, I selected the ability to change the aircraft, but that was only after nothing happened the first time I tried.

I'll report back on how I go.

[edit][timestamp=1384777234] - I've redone it all, but I still have the same problem. :([/edit]
