A notebook was found after our invasion of Afghanistan that had one page entitled "Explosivija za Oklahomu," which means "explosive used in Oklahoma" in Serbo-Croatian ("Bojinka" is also Serbo-Croatian, for "big explosion.") That page contained a description of a formula for a bomb including both ANFO and dynamite. Just such bombs were used against our East African embassies, according to Bodansky, and the explosions resulting, like the OKC explosion, had secondary shock waves that were stronger than the initial blast.

I am familiar with this. In 1993, the bomb manuals brought into the country by Yousef and Ajaj had instructions on making ammonium nitrate dynamite, but I don't believe they had the ANFO bomb design (as of this time, I am still tracking this).
