What It's Like to Pilot a Colombian Narco Submarine

Spiegel has an incredible profile of one man who piloted one of the many custom-built submersibles used by Colombian gangs to transport drugs. It sounds like a miserable experience, as these boats are decidedly low-tech. They're built fast and cheap without amenities for the crew.

The boat was divided into three sections. A hatch in the bow led to the cargo hold, which was barely a meter (3 feet) high. The crew had to crawl through the cargo hold on hands and knees, passing the packages of drugs, to reach the control station and the sleeping berths.

Alonso positioned himself at the wheel, next to a GPS device for navigation and a radio. The diesel tanks were underneath the berths. The engine room, containing two turbo diesel engines, was behind Alonso. There was no light, there were no toilets, and there was barely enough room to stand up or lie down to sleep.

At around 8 p.m., the tide was high and the night sufficiently dark as the ocean water tugged at the submersible. A speedboat pulled the vessel out to sea, where the crew started the engines. They accelerated to 12 knots and set off on a 270-degree course heading west, toward the open ocean. The guard provided by the drug mafia for each transport, armed with a revolver and an assault rifle, stood at the door to the engine room. It was incredibly hot in the submersible, where the engines remove oxygen from the air and enrich it with carbon monoxide, despite ventilation pipes.

"You constantly feel like you're suffocating," says Alonso. "Every four hours, we reduced the speed from 12 to six knots. Then we opened the hatch in the front for exactly one minute, let some fresh air in and accelerated again." The four-man team worked in shifts, while Alonso kept monitoring the route. Once they were in the open ocean, the man with the assault rifle gave him a piece of paper showing the target position. Their instructions were to arrive there on a specific day and at a specific time.

Each of the men tried to sleep after his shift, but the stench and the noise on board made this impossible. They had to drink copious amounts of water to make up for the buckets of sweat constantly running off their bodies. Their main source of nourishment was condensed milk, the Peruvian "Leche Gloria" brand. The stench from fecal matter, which couldn't be disposed of during the trip, soon became almost unbearable.
