Undated image released by the British Army Monday Feb 4 2013 of Sergeant Scott Weaver, of The Queens Royal Lancers launching a newly issued Black Hornet miniature surveillance helicopter during an operation in Afghanistan. The Scandinavian-designed Black Hornet Nano weighs as little as 16 grams (0.56 ounces) — the same as a finch. The four-inch-long (10-centimeter-long) helicopter is fitted with a tiny camera which relays still images and video to a remote terminal. Troops used the drone to look for insurgent firing points and check out exposed areas of the ground before crossing. (AP Photo/ Sgt Ruper Frere) less
