> What is "pyro sdafing" ? A typo :-). BUT you'll find "pyro safing" in the precise context that I intended it in the following references It means "making sure that things that are meant to go woosh and/or bang at intended times don't do so at unintended times". http://www.nasaspaceflight.com/2008/12/endeavour-to-visit-three-states/ http://www.nasaspaceflight.com/2009/05/endeavour-rollaround-atlantis-depart= ing-california/ http://lsda.jsc.nasa.gov/books/apollo/s5ch1.htm ___________________ Here you get 20+ uses of "safing" including the glorious - Comment: How is the =93Drag Chute Pyro Safing=94= in the Safing Sequence different than the =93Drag Chute Safing=94 during the initial Safing Processes? That's something like "How much wood would a wood chuck chuck if a woodchuck could chuck wood?"
