Ewan and Charley swap their e-Harley Davidsons for plane first and follow it up with a journey by ship to Panama. McGregor's bike needs some repairs and will be fixed by the time they reach Costa Rica. The ship they travel in with the bikes looks like a beaten-down vessel that raises genuine concerns about making the journey in one piece. The boat crew looks sharp and proactive while trying to make the show crew's journey as comfortable and safe as possible. The episode also introduces Nuqui, one of the wettest regions in the world where the ship quickly makes a pitstop to fuel up on essential supplies.

The film tells the story of the ill-fated Nazi Land Speed record attempts. This is a story of engineering excellence, Grand Prix racing, Nazi propaganda, celebrity, and an intense rivalry which would leave a speed record unbroken for 79 years and one of Nazi Germany's best racing drivers dead. During the rise of the Third Reich two German car manufacturers were ordered to build the most high performance vehicles the world had ever seen. What followed was a rivalry that would reap Grand Prix victories, international domination that was a propaganda coup, and provide world fame to its drivers who risked their lives smashing speed records that would stand for 79 years. All under the direct orders of the Fuhrer himself.
Bugatti and Alfa Romeo dominated racing before 1934. But the years from 1934 to 1939 were six tumultuous years in which Grand Prix racing was dominated by the German Auto Union, the arranged marriage of Audi, Horch, Wanderer, and DKW, and Mercedes-Benz teams and provided a spectacle of speed, sound and fury never previously attained and never since matched. There are few periods of racing that have excited as much interest, event attendance and sophistication of equipment as the era of the Silver Cars. They were so far ahead of their time that many of their accomplishments were not duplicated until Mercedes went racing again in the early 1950s. There is also something about men who faced the challenges of staying in a cockpit of a highly sophisticated machine capable of 200 mph with no safety systems. They were giants and among them were Italian Tazio Nuvolari and two greatest German pilots of the thirties, Rudolf Caracciola of Mercedes and Auto Union's Bernd Rosemeyer who duelled with faster, more innovative and sleeker machines, developed in wind tunnels.
This special documentary charts the rise of Nazi Germany's dominate 'Silver Arrow' Grand Prix and Speed Record cars of the 1930's. Leading motor racing and World War 2 experts James Holland, Richard Williams, Eberhard Reuss and Chris Routledge tell the story of the Nazi funded Auto Union and Mercedes Benz 'National Racing Cars'. Hitler's Supercars interweaves the rise of the Third Reich with the racing exploits it funded and what propaganda messages these racing cars where sending.

The International Space Station is the ultimate extreme home. Costing $150 billion, it is the most expensive structure humans have ever built, in the most inhospitable environment known to man, with no air food or water. Assembled at 250 miles above the earth, it's an epic engineering challenge. We're going to take it apart and uncover what's going on inside the ISS.
Its superstructure secrets will help our species reach other planets and beyond. Using photo-real computer graphics, we take it apart to uncover the extraordinary innovations that enable it to support life in the deadly vacuum of space.

NASA is on a mission to send humans to Mars within just 15 years, but to reach this next frontier of space exploration, experts must discover new technology and cutting-edge science that protects astronauts from the Red Planet's deadliest killers.

'2040' is an innovative feature documentary that looks to the future, but is vitally important now. Award-winning director Damon Gameau embarks on journey to explore what the future would look like by the year 2040 if we simply embraced the best solutions already available to us to improve our planet and shifted them into the mainstream. Structured as a visual letter to his 4-year-old daughter, Damon blends traditional documentary footage with dramatized sequences and high-end visual effects to create a vision board for his daughter and the planet.

A look at two missions attempting one of the most difficult feats of space exploration - to collect a rock from another world. The film checks in on the US and Japanese attempts to bring a piece of an asteroid back to Earth. The missions have taken decades of planning, but the results will be worth it. We find out how studying these space rocks can teach us about the origins of our solar system and may one day help save Earth from a catastrophic collision.
