CORPUS CHRISTI, Texas — Smugglers flying small cocaine-packed airplanes toward the United States from South and Central America might make it to Mexico thinking they went undetected by American forces staked out in international waters trying to interdict them.
But once on the ground in Mexico, from where they hope to smuggle their contraband into the United States, those tiny planes will be greeted by a swarm of Mexican law enforcement. What’s more, they will never know a Department of Homeland Security plane was flying within 100 feet of them, quietly tailing them over the Eastern Pacific or Western Caribbean and then tipping off Mexican authorities.
