Anaheim, California - Conspiracy freaks, hold onto your tin hats.
Darpa, the Pentagon's far-out research arm, may have publicly abandoned its creepiest programs, like Total Information Awareness. But the agency, as shown at its DarpaTech conference, still has a project to make you run full-speed into your bunker.
Mighty IsisDarpa wants to start planning for a blimp, three times the size of Goodyear's, that would keep watch over an entire city.
Hovering 70,000 feet above ground, the ISIS (PDF) airship (short for Integrated Sensor Is Structure) would use a giant, flexible radar antenna to give, in the words of Darpa program manager Larry Correy, a "dynamic, detailed, real-time picture of all movement on or above the battlefield: friendly, neutral or enemy."
