The article is written as if the whole sky resort looks as in the picture. While they actually tried to fix some patches of the route which had to few snow. Usually they fix it by moving snow around with a plow. Which they can not because the snow is to thin currently. Also they aborted after trying 9 times, because it was not economical.

I totally agree to the absurdity to transport snow with a helicopter. However it's a big difference between what people expect when reading this article to what really happened.
