I'm trying to remember where I read about Airbus designing the plane in two different places and when they built the thing it turned out that one place was using version X-1 and the other X and that caused really subtle problems with alignment. I'm sure it was Airbus but I can't find the article. EDIT: Found it http://calleam.com/WTPF/?p=4700 http://calleam.com/WTPF/?p=4700 Offtopic but the "Catalogue of Catastrophe" is a damn good read http://calleam.com/WTPF/?page_id=3 http://calleam.com/WTPF/?page_id=3 Basically a "why things failed/cost a fortune that shouldn't" list for large projects.
