single computer crash on Saturday in the Customs office of LAX caused hours of delays for more than 17,000 airline passengers. US Customs officials say that a malfunctioning network card on a single desktop created a "domino" effect with its other computers, leading to a total system failure that caused massive wait times. According to a Customs spokesman, "We lost access to our national systems, as well as our local area network." He went on the claim that it took over ten hours to diagnose the problem, halting screening operations and leaving passengers stranded on planes or in the airport -- unable to enter or leave the US. From the sounds of it, Customs need to hire a handful of Engadget readers, who we're pretty sure could have located the source of the problem in considerably less time.
