Former EOD man Blaster has been following reports on the sarin shell since its discovery two weeks ago. About to conclude the investigative trail led nowhere, Blaster overheard a CNN interview with current Iraqi Survey Group head Charles Duelfer last Wednesday. Later that day, Blaster found a press release from the ISG. Bottom line: the shell is pre-1991, probably constructed around 1988 when Iraq is believed to have begun field tests of binary sarin shells. The armament was not destroyed by UNSCOM, nor did Saddam declare its destruction. And the shell's origin could very well have been an existing stockpile.
