Terrorism has become the scourge of the 21st century. In the post-9/11 world we live in a state of heightened paranoia: will the next attack be today? Can it be stopped? In this programme, we investigate the latest cutting-edge technologies that are pushing the limits on the war on terror. We investigate new "bomb-sniffing" buses that can potentially stop suicide bombers in their tracks, look at buildings that can actually 'brace' for impact and see the development of "smart" guns that can shoot around corners. Using dramatic reconstruction and CGI we try to deconstruct the anatomy of some of the world's most notorious terrorist strikes and demonstrate how high-tech weaponry and defence systems could have lessened the effects of the attacks - or prevented them altogether.
