Bernd,
Nobody is calling for the punishment of these guys. At least not as far as I'm aware. Sure they made a mistake, and honestly they could and should have known about the situation. But they are human and humans make mistakes. I don't expect the airline to do anything more than a thorough debriefing with the training department to be quite honest with you.
It's not the first time pilots landed where they weren't supposed to. But the responsibility shouldn't just be shrugged off as "oh the runway was marked improperly" or whatever the newspapers were trying to suggest. It was all pretty clear and well documented and published. One would reasonably expect for them to have known this and prepared for it. It never would have ended up this way. But now that it did, take responsibility and man up to it. That's all.
