Impossible Repairs - Episode Guide

Host Mike Davidson heads deep into the forest of the Pacific Northwest for the final leg of a dangerous six-week, heli-logging mission. For five days, he will bring his cameras-and airsickness bags-aboard an S64 Air Crane, one of the biggest and strongest helicopters on Earth, as it hauls millions of pounds of timber from the forest. It's a job that promises a big payday...and even bigger challenges, with heavy winds, dense fog, and mechanical failures that will keep the maintenance technicians and aerosystems experts busy from start to finish.

Host Mike Davidson is crisscrossing the rails across Eastern Europe on a 24/7 cargo operation powered by Soviet era locos. The mission: to transport potash—a potassium rich fertilizer—to massive ships, which in turn will deliver the cargo to over one hundred countries worldwide. This is a multimillion-dollar business, and the pressure is intense to keep the trains moving…even when there are problems. Thankfully, there are resilient crews that keep this rail network and locomotives running, no matter how big the challenges are.

Trains may seem old fashioned, but they still make the world's economy go, and SBB Cargo International is one of Europe's busiest haulers. Host Mike Davidson joins a freight run carrying a million-dollar payload, from a busy container yard in Italy, though the Alps of Switzerland, across a labyrinth of tracks in Germany, to the Port of Rotterdam in the Netherlands. Along the way, he'll follow locomotive drivers, maintenance crews, and engineers working around the clock to keep everything rolling on a route that throws challenges at every turn.

Every year, more than 14,000 ships pass through the Panama Canal, but when shipping companies need to move a small number of containers across the continent, it's much cheaper to send them on the railway. Host Mike Davidson heads to the jungles to transport precious refrigerated cargo on the Panama Canal Railway. Keeping these metal monsters running and the 47-mile line clear is no small feat, but fortunately there's a dedicated team putting everything they have into this railway, from last-minute track repairs to infrastructure overhauls.

Offshore fish farming is big business, with big profits, big machines, and very big risks. In this episode, host Mike Davidson goes on perhaps his most physically demanding mission yet, joining the crew of Open Blue as they transport a school of Cobia whitefish worth $300,000 in future sales. For three days, he'll battle ocean waves, dive in shark-infested waters, and assist in excruciating repairs to ship engines and feeding dosers. And just when it looks like smooth sailing ahead, Mother Nature steps in to show who's really in charge.

Host Mike Davidson is heading under one of the world's largest lakes for a multi-million-dollar tunnel-boring project. The crew's mission: to give Toronto's wastewater system a major upgrade, using a highly sophisticated machine capable of creating a tunnel with a diameter greater than a two-story house. But big machines often require big repairs. Witness the epic battles happening 260 feet below the Earth's surface as our hard-hat heroes battle challenge after challenge to keep this operation running on budget and on schedule.
