tried to fly choppers during storms for search and rescue, however, in this case, the Chinese PM wasn't there to save anyone, but a PR (I am not saying this is merely a show, it is a very important for the leader to show they care). It is very risky. It makes more sense for him to take a safer route. Of course, since I don't know the weather condition there, I can't really comment on it. I just want to say the difference between the aftermath of 9-11 and the current situation.
