someone else will have to help with the syntax, but this is a fairly easy problem....
And there is prbably another way, there always is with this game...
Give the Aircraft a unique name. We'll say jet1 for this... And ther pilots name can be, aww, i dunno... Jeff...
Have a switch trigger where in its condition field have the line (again, syntax not withstanding) jet1 canmove and sycronize that with a waypoint telling the pilot where the jet is and to get in it...
The above is flawed, and somewhat tedious, but it would work
