Many argue that flying saucers and other extra-terrestrial space ships continuously visit the earth. If that were true, what kinds of technologies would such alien spacecraft require? And do eyewitness reports of UFO sightings jibe with modern theories of how interstellar travel might be possible? Authors, astronomers and theoretical physicists weigh in with the blueprints for inertia-canceling devices, nuclear-powered craft, antimatter propulsion systems and even warp drives. Based on Einstein's theories and countless scientific studies, we'll find out how these visitors might bridge the vast distances between the stars. And if they could survive such hazardous journeys, are they flesh and blood or intelligent machines?

Director James Cameron returns to the site of the 1912 wreck of the RMS Titanic. With a team of history and marine experts he embarks on an unscripted adventure back to the final grave of 1,517 people. Using two small, purpose-built remotely operated vehicles, we can see inside the Titanic and with the help of CGI, view the ship's original appearance superimposed on the deep-dive images. Throughout the movie, there are re-enactments of events that are discussed that use CGI recreations of the interior of the Titanic. The documentary was named one of the Best 3D movies ever by Rolling Stone.

In the 1960s, US President John F Kennedy proposed landing a man on the moon before the decade was finished. This film has interviews with most of the surviving astronauts of the Apollo program who were making ready to make that great voyage with an army of experts determined to make the endeavour possible. Through training, tragedy and triumph, we follow the greatest moments of one of Humanity's great achievements. The documentary reviews both the footage and media available to the public at the time of the missions, as well as NASA films and materials which had not been opened in over 30 years.

Ewan McGregor and Charley Bormann are very close to finishing their journey. Discussions on security are still on the agenda; they cannot travel at night due to dangerous cartels. They will need to do many miles on a bus with space for the bikes inside. The team manage to get the bikes on after concerns they wouldn’t fit. Repairing and conditioning the bus is an achievement considering they did it in a few days.
Ewan and Charley get back on their bikes, and they head to their last border cross to enter the United States. After 12 hours in the border, the crew, Ewan and Charley make it to America. It’s an easy stretch to L.A. on their bikes. Ewan, the crew and family, finish the last leg. It’s done, they’ve managed to finish Long Way Up. It’s such an achievement. Episode 11 is a heartfelt finale, showcasing the end of an incredible journey from both Ewan, Charley, and the team that supported them.

Rockefeller, Carnegie and Morgan team up to help elect William McKinley to the U.S. presidency by paying for his 1896 campaign, to avoid a possible attack on monopolies. However, fate intervenes when McKinley is suddenly assassinated, and vice president Theodore Roosevelt assumes the presidency and promptly begins dissolving monopolies and trusts in America. Meanwhile, Morgan buys out Carnegie Steel to make Carnegie the richest man in the world, and Henry Ford designs an affordable automobile with his Model T and starts his own business, Ford Motor Company, which sets a new business model for companies to follow.

To fly like a bird, Earthflight not only captured remarkable images of wild flocks but also relied on some extraordinary relationships between people and birds. Filmed over four years, in six continents and more than 40 countries, the Earthflight team used many extraordinary techniques. For some of the unique flying shots, members of the team became part of the flock. The birds followed wherever they went - even in a microlight over Edinburgh and London. In Africa, paragliders floated alongside wild vultures, while a model vulture carried a camera inside the flock. In South America, wild-living macaws, that were rescued as babies, still come back to visit their 'foster mother' as he travels along a jungle river. In Africa, a radio-controlled 'drone' silently infiltrates masses of pink flamingos without disturbing a feather, and microlights and helicopters capture the dramatic moment white storks arrive over Istanbul. In Africa a tame vulture carried a camera across the African bush and recreated the behaviour of his wild relatives. Similarly, in the USA, a flock of hand-reared snow geese followed the migration route of wild flocks and took in the sights and sounds of New York - managing to get lost in Brooklyn
