UK sends hand-held drones to Afghanistan BRITAIN'S military says its soldiers in Afghanistan have been issued with surveillance drones so small they can fit in the palm of a hand. The Scandinavian-designed Black Hornet Nano weighs as little as 16 grams. The 10-centimetre-long helicopter is fitted with a tiny camera which relays still images and video. The military quoted Sergeant Christopher Petherbridge, with Britain's Brigade Reconnaissance Force, as saying troops used the drone "to look for insurgent firing points and check out exposed areas of the ground before crossing."
