No need to read further. Come back when you actually have a grasp of the situation. It is unprecedented.
why do you think the word “unprecedented” means “impossible to deal with”? It just means that we haven’t had this specific situation before.
I deal with unprecedented situations all the time — you’d be surprised how often things happen that either haven’t happened before, or at least not in the context of what you are working.
people solve “unprecedented problems” all the time.
Last year’s BP oil spill was “unprecedented”. They solved it. And frankly, in terms of difficulty, the possibilities for the situation there being “unsolvable” was higher in my opinion than in this case.
