On a sidenote to HB-IQF:
you didn't reveal the name of the german airport you were talking about, but you gave an important clue
And BTW, in Swiss news I only heard of one german airport, where that happened.
But that was only a sidenote. Where there are people, there will be errors made. Athen was blocked by the snow. So what? happens all the time in other airports, and much worser things happen as well. I wouldn't exagerate only because of the snow at ATH.
