Not all building collapses were engineering failures.
The WTC collapse was not an engineering failure. I figure a disclaimer should be placed here to clarify that, since it currently shows under Engineering failures through this page. CodeCarpenter 17:00, 28 December 2006 (UTC)
Disclaimers of any kind are against WP policy. Check the WTC articles again, only some of the structures are in this cat. Kevlar67 (talk) 00:24, 10 January 2008 (UTC)
