This morning in the LA Times, the business section had a big article on Airbus' woes, and blamed it on the CAD software: http://www.latimes.com/business/la-fi-airbus9oct09,1,4119560.story?coll=la-h... "In designing the plane, German engineers in Hamburg used older versions of design software based on the Unix operating system while their counterparts in Toulouse ran a newer Windows software." This drive-by blaming of the operating system (which might be read by some as "unix is so crappy it can't run the latest cad software") I found less misleading details online at http://aecnews.com/articles/2035.aspx which said Airbus foolishly used Catia v4 in some locations and Catia v5 at others even though their file formats are incompatible, and didn't invest in conversion software. http://www-306.ibm.com/software/applications/plm/catiav5/sysreq/ shows that Catia v5 is available for Unix as well as Windows. So the whole unix vs. windows thing in the LA Times is a canard. The reporter who wrote the story often reports on aerospace stories, but lacks enough software knowledge to be able to filter out inaccurate info from his sources. C'est la vie. - Dan
