Homeland Security is taking its fight against drug smuggling to the sky.
The Associated Press reports  that CBP agents are using aging P-3 surveillance planes with high-tech radar to search for drug smugglers.
The surveillance comes at a time when agents are finding an increasing amount of cocaine smuggling across the Caribbean to the U.S.
In fact, the DEA estimates that cocaine smuggling has increased from 60 tons of the drug to about 100 tons in the past several years.
One reason: Smugglers are finding the Caribbean to be one of the easiest ways to bring the drugs to the U.S.
