Statement: “It was just after midday in San Diego, California, when the disruption started. In the tower at the airport, air-traffic controllers peered at their monitors only to find that their system for tracking incoming planes was malfunctioning. At the Naval Medical Center, emergency pagers used for summoning doctors stopped working. Chaos threatened in the busy harbour, too, after the traffic-management system used for guiding boats failed. On the streets, people reaching for their cellphones found they had no signal and bank customers trying to withdraw cash from local ATMs were refused,” New Scientist magazine wrote March 6, 2011.
Analysis: New Scientist, a magazine based in Great Britain, seemed to have uncovered a major incident in San Diego, one that received no local media attention at the time. According to the magazine, a global positioning system outage happened because the Navy accidentally jammed GPS signals in downtown San Diego.
