Is there any chance for FS2Crew to take control of PMDGs ground service vehicles in a future update?

It looks somewhat odd to miss them again after using PMDGs own turnaround for such a long time.

It's good idea.  We can control the ground vehicles via the FMC.

Not the most elegant way, but it works.

Of course, we'll have to add an option to shut them off.

We'll look at that for SP1.

Thanks for the input!
