The ship was equipped with a network of 27 dual 200 MHz Pentium Pro based machines running Windows NT 4.0 communicating over fiber-optic cable with a Pentium Pro based server. This network was responsible for running the integrated control center on the bridge, monitoring condition assessment, damage control, machinery control and fuel control, monitoring the engines and navigating the ship. This system was estimated to save $2.8 million per year by reducing the ship's complement by 10%. In 21 September 1997 while on maneuvers off the coast of Cape Charles, Virginia, a crew member entered a zero into a database field causing a divide by zero error in the ship's Remote Data Base Manager which brought down all the machines on the network, causing the ship's propulsion system to fail.
We can predict everything, except the future.
