The comment concludes with this analogy:
I feel like I've been arguing for years with people who believed that they knew about a super-sophisticated way to travel across America: by horse and buggy. And I've been arguing that it is absolutely ridiculous to believe that anyone would ever travel across America by horse and buggy. And now we've suddenly both been been informed that there was a time, many many years ago, when lots of people actually did travel across America by horse and buggy.
Live and learn.
Ed, your comment is inconsistent with the fact that the method used to create the Dugway simulant has been used since 1998 in making simulants. For example, it was the method used to make the Dugway simulant used in the Canadian aerosol study done after the threatened use of anthrax in connection with the detention with Vanguards of Conquest #2, Mahmoud Mahjoub.
The study results issued on September 10, 2001. The study found that the simulant leaked from the envelope before opening and that it immediately dispersed to the other side of the room upon opening.
Here is authority for the proposition that your “horse and buggy” comment makes no sense. The same Dugway simulant was currently being used in aerosol tests re the anthrax threat posed by the islamists. See February 2001 PDB. See also Science article describing mixing at the Wisconsin dairy processor. It leaked from the envelope before opening and immediately dispersed throughout the room.
