The plant makes Cyclododecatriene which is used in the production of polyanhydride resin, PA-12, which is used to make brake and fuel lines for automobiles. The explosion means that there is only ninety percent of the world's supply of PA-12 that manufacturers were counting on. It will be interesting to see if this issue is resolved quickly or becomes a major event.

Bush era. The NASAspaceflight.com website gives word that a preliminary report released yesterday recommends a shuttle-derived option but warns that no option meets the ambitious timetable at the specified budget.
Booster-heads will be interested to learn the three heavy-lift approaches under study: 1) Shuttle-derived, 2) a Saturn V-inspired kerosene / liquid Hydrogen throwback or Falcon XX muscle missile, and 3) a scaled-up EELV." top

While not as stimulating as a needed freeway interchange or clean energy plant, the slow rate of IPv6 adoption may equally hamper the next stage of economic expansion. Now, how to sell this idea to the stimulators?" Link to Original Source top

By traversing topic trees or keyword searching Google Groups, I was often delighted to learn that my wide-ranging quests had already been answered, or at least I could find an audience receptive to those questions. This seems no longer true for Usenet, and Google searches of the entire Internet do not seem to uncover similar sects. Has anyone adequately explained the fall of Usenet? Is there a new, improved way to find and communicate with scattered peoples who share a common interest?"
