After research and development to the tune of US$19bn, the Pentagon concludes that nothing detects bombs more effectively than a well-trained dog; Uxo would be proud.

Despite a slew of bomb-finding gagdets, the American military only locates about 50 percent of the improvised explosives planted in Afghanistan and Iraq. But that number jumps to 80 percent when U.S. and Afghan patrols take dogs along for a sniff-heavy walk.

Technology isn’t the answer to every problem… unless that problem is “how can we squander billions of dollars that could be better used in other ways”, I suppose.
