The war on terror is about to get a deadly new weapon. U.S. scientists are testing a 5-lb missile “the size of a loaf of French bread” in the California desert, that packs enough explosives to blow up a pick-up truck. The tiny innovation will mean that currently unarmed spy drones will acquire massive firepower, and allow the larger Predators to carry even more missiles as they scour the skies over Afghanistan. But are these weapons really that impressive? James Bond had them years ago.
