When the pilot of a Colombian drug-smuggling plane landed at a clandestine airstrip in the vast Amazon rainforest, his every move was being watched from high up in the sky.Guided by a high-tech spy-plane circling thousands of feet above the clouds, Brazilian police arrested the pilot minutes later and confiscated 300 kg of cocaine. Police hope the bust, which took place several weeks ago, will soon allow it to lock up an entire international drug gang.In the face of growing international pressure to better preserve the Amazon, Brazil is increasingly betting on intelligence and technology in its uphill battle to tackle illegal activities.
