LONG BEACH, Miss. - South Mississippi's QinetiQ/PSI has been quietly working on an impressive list of cutting edge products at its 25,000 square-foot facility, including a shoulder-mounted system that detects the location of snipers, a device that checks for explosives at airports and a system that makes aerial supply drops more accurate. And those are just the systems it can talk about. (Source: Alliance Insight, April 2009)
