Why is training and documentation important? Well, it isn't rocket science. Here's an excerpt from a NY Times article. Note especially the last paragraph. To read the whole article, see http://www.nytimes.com/2003/07/09/national/nationalspecial/09SHUT.html (You need to register but it's free.) -- Michael West Melbourne, Australia Earlier Shuttle Flight Had Gas Enter Wing on Return --------------------------------------------------- The space shuttle Columbia was not the first to have superheated gas invade its left wing on re-entering Earth's atmosphere, according to documents released yesterday by NASA. In 2000, the documents show, the shuttle Atlantis went into orbit with a quarter-inch breach in the wing's leading edge, allowing blowtorch-hot plasma into the wing on re-entry. But unlike the accident that destroyed the Columbia on Feb. 1 and killed its crew of seven, the incident resulted in only minor damage, leaving the wing's inner structure intact. They say the gap in the leading edge of the Atlantis wing was created because workers installed insulation improperly during an overhaul in Palmdale, Calif., in 1997. A NASA spokesman, Allard Beutel, said the only damage discovered by NASA after the flight was to the piece of insulation itself. "The only component that needed to be replaced was the butterfly gap filler seal that was installed improperly in the first place," Mr. Beutel said. The entire shuttle fleet was inspected for similar problems, and workers received new training in installing the part "to make sure that it never happened again," Mr. Beutel said. ************************************************** To post a message to austechwriter, send the message to austechwriter@xxxxxxxxxxxxxx To subscribe to austechwriter, send a message to austechwriter-request@xxxxxxxxxxxxx with "subscribe" in the Subject field.
