In an article in "The Atlantic" entitled "The Lessons of ValuJet 592," William Langewiesche presents a case in which the May 11, 1996 crash in the Florida Everglades as an example of a system accident, in which the complexity of the overall operation was the major contributing factor. Taking a contrary position, Brian Stimpson argues in the "Manitoba Professional Engineer" that there are other examples of studied complex operations which have been routinely performed safely for many years, with such examples including large aircraft carriers and the Diablo Canyon Nuclear Power Station in California.
