Bidule,
this has nothing to do with "support for my German colleagues", and yes, I will say the exact same things for almost any other airline.
And so what would you do? Just blame the pilots and be done with it? And hope that by deterrent you keep all other pilots from making mistakes. Good luck with that.
"Oh, maybe someone could mistake that rectangular area prepared for the landing and takeoff of aircraft as a runway. But that's ok, if they do it we'll just punish them, and everyone will be safe."
