Hi there Randomslap,
First of all, cool that you made a portover of the C-17. Thank you for that.
Now, i've tested the mod and i found the following bugs/glitches.......
1) Except for the cargodoor at the back, it is possible to walk through the airplane as if you were a ghost. No matter what angle i take...even when i'm inside the airplane i can just walk trough the walls.
2) When i'm flying and i land the airplane and then shut down the engine, the sounds keeps on going...it doesn't stop.
I've tested it in the editor not on multiplayer but i can imagine that these bugs will also appear in the MP.
Other then that, i haven't realy come across major bugs/issues.
