flyburg, my comment was a follow on to Good Memories comment that "If on top of that you have to familiarize with the local deicing procedures and communications this could be too much and lead to accidents and incidents."
For the klm crew this was a home game. If on the other hand, as you suggest, the ground crew gave an erroneous "all clear" then the poor show was theirs. Either way not a good result for the lowlanders.....
