It seems extremely unlikely that a nerve-gas shell would be physically indistinguishable from a regular one. This does not sound like a good thing during a war.

I remember Kay saying that these shells were stored with regular ones, and there were hundreds of such storage sites. At the time of his comment, they had examined only a few.

I also recalled since my last post on this subject that many binary artillery shells are designed to actually mix the binaries after the shell is fired, and make it very difficult to do so otherwise. A good safety feature. If Iraq's shells are like this, it might make it hard for the insurgents to "premix" a shell before using it in a bomb. Good news.

Maybe they will try opening the shell and mixing the material outside. That should be interesting. Will mysterious sarin corpses start showing up soon?
