The danger in ANFO is not from shattering brissance, but rather from overpressure. Some of the things I've seen and read about ANFO have said that for terrorist attacks on buildings it might actually be _more_ dangerous than higher order explosives because of its more sustained pressure wave. The shockwaves generated by the higher order explosives are more easily reflected from building structures, whereas the longer lived pressure wave from ANFO doesn't reflect as easily and tends to push structures over. In an interview Stacey Loizeaux of Controlled Demolitions said there was only one intact column left in the Murragh building in Oklahoma City after it was blown up, so apparently ANFO can be pretty effective against concrete structures. In the end I suppose it's like the difference between getting punched in the face by Mike Tyson versus getting body slammed by Warren Sapp. Tyson's punch is penetrating and shattering, but Sapp's body slam will leave you mashed into a depression in the turf. Neither one is likely to leave you in very good condition afterward. As far as ANFO's connection to biofuels goes, I suppose if you washed enough ammonium nitrate out of a _large_ quantity of chicken feces you could mix it with biodiesel and call it BANFO. <humor> When you aren't using it for blowing up oil companies you could burn it to cook your food while you're living in your tarpaper shack in the Montana wilderness. Ecoterrorism indeed. ;-) </humor> Alan Petrillo -- He who sows the wind shall reap the whirlwind. Remember the World Trade Center. ------------------------ Yahoo!
