the site in question is:
wtc2002.com i tried searching for information on it being a hoax on a few sites, including google and yahoo, and was still unable to find any relating documentation on that.
if anything, i think its more than likely fox news got the story wrong, and cnn and msnbc carried it correctly (i.e; its not a hoax).
here's a semi-recent news article on it from yahoo news:
