I too, would love to read the document when it's ready.

I always think this sort of thing is like trying to work out the odds of you winning a raffle.
You may have some sort of idea how many people are entering it but you're really just guessing.

Am I the only one who feels uneasy that some committee somewhere will shelve plans to tackle this on the grounds that "Ahhh! It'll probably be all right"

I read a book called "From Exodus to Arthur" (it's not brilliant, once it starts geting to conjecture to be honest and it reaches that point fairly early).
One good thing about it is the fact that ancient myths, legends and writings have the remote possibility of being impact events if they are origined on anything other than utter fable.
Even if just a one of the old legentd come from impact stories and comets, it raises questions over just how often Tunguska events may happen.

(the best bit of the book is the pretty thorough explanation of dendochronology and a paragraph that points out that all our climate change data for the last 100,000 years comes from just 4 ice cores and there are gaps. Now there really is no reason for you to buy it).
