Pentagon tests toxin detection and forecast system
News & Analysis  
4/30/2004   Post a comment
The blimp with the 23-foot-long sensor-studded tether that is now hovering over the Pentagon is about to conduct novel tests of simulated airborne toxins. As the blimp releases a faux poison over the course of the next two weeks, a real-time system designed for first responders will gauge how much of the toxin has been discharged and where, and then predict where the plume will drift and how it will disperse.
Robots readied to take on search-and-rescue duties
