Well Wheelchock, Maybe those guy's didn't have the proper papers on board...???
When an airport authority tells you (or colleage) to ferry a plane empty to a place where things can be repaird you are allready with the wrong company, even worse is that they didn't notice it themselves... That kind of pilots should only fly over restricted aera's like the ocean or desert..., but if I where you I wouldn't bother to come back to Holland again, that way I can sit and relax in my back yard instead of hiding in the shelter when one of your company planes fly over...
