This is where I got the K-Ship 3D model a ways back.
I got written permission at that time and have the original files and textures.

I believe even in GWX the K-ship will fall out of the sky if it drops below a certain speed.
Took me quite a while to get it working as it does for SH3.
It was the mod I was working on at the time that got me invited to join The Grey Wolves Team.
