Rangers look at an anti-poaching aircraft named Seeker, which is being shown to reporters at the Kruger National Park, December 4 2012. South Africa has taken its war against rhino poaching to the skies by deploying a high-tech, low-speed reconnaissance aircraft to detect illegal hunters before they strike. Home to nearly all the continent's rhinos, the country is on the frontline of a poaching war where criminals with high-powered weapons, helicopters and night vision goggles have been killing the animals for their horns, which sell at prices higher than gold in Asia as a traditional medicine. The anti-poaching aircraft is equipped with sophisticated heat sensors to detect animals and humans on the ground, and a quiet engine.
