Jimenez and the man holding the rocket moved at the same time. Mike Trono lit off the Stinger missile the same instant the Argentine soldier unclipped his safety harness. The rocket’s infrared system only had a fraction of a second to come to life, find the heat plume billowing from the helicopter’s exhaust, and make a minute adjustment. Jimenez leapt from the chopper just before the missile slammed into the turbine housing directly below the spinning rotor. The six-pound warhead detonated. The bulk of the engine saved Jimenez’s life, but he was still caught in a flaming overpressure wave that ignited his clothing and slammed him into the water as if he’d jumped from twice the height. Had he not landed feetfirst in the roiling waves churned up by the RHIB’s outboards, the impact would have been no different than landing on cement. The water extinguished his burning uniform and prevented the burns on his face and hands from going past second-degree. He came thrusting back to the surface, coughing up a lungful of river, his skin feeling like it had been dipped in acid.

Fifty feet ahead of him, the Eurocopter crashed into the river, smoke pouring out the doors and blown-apart windshield. Jimenez didn’t have time to fill his lungs, as the craft tipped and the rotors hit the water. They came apart like shattering glass, shards of composite material filling the air. Several skimmed across the river surface inches above Jimenez’s head and would have decapitated him had he not ducked under the waves.

Through the water he could see flames licking at the chopper’s shattered carcass, a wavy, ethereal light that silhouetted the pilot still strapped in his seat. The dead man’s arms swayed in the current like tendrils of kelp.

He struggled to the surface once again, the roar of fire filling his ears. Of the RHIB, there was no sign, and with the chopper down and the border patrol’s two Whalers destroyed the thieves had a straight run to Paraguay. As he started the painful swim to shore, his burned hands screaming with every stroke, Lieutenant Jimenez could only hope they would be stopped before they could sneak across.

“NICE SHOT,” JUAN SHOUTED as the Argentine helicopter fell from the sky in their wake.

“That was for Jerry,” Trono said, laying the Stinger on the deck to reload it with the second missile stored in one of boat’s several secret weapons caches. Mark Murphy was at the bows, watching for anyone else coming at them. He asked, “Are we still going to stick to the original plan?”

Cabrillo thought about it for a moment. “Yeah,” he replied. “Better safe than sorry. The cost of the RHIB will just become one more line item in the CIA’s black budget.”
