David Attenborough concludes his epic history of the evolution of flight with an exploration of the highly advanced fliers that dominate our skies today – the extraordinarily diverse skills of the birds, and the sonar-guided precision of the bats. He encounters some of our planet’s most remarkable fliers – from peregrine falcons dive-bombing starlings over Rome, to hummingbirds hovering in the cloud forests of Ecuador. In a spectacular finale, he visits Gomantong cave in Borneo to witness the mass exodus of a million bats.

The 80s was also an age of innovators and icons, of style and substance. In this chapter, Dylan Jones celebrates some of the stars who created the timeless legacy of the 1980s. From stellar BBC archive performances from the likes of Madonna, Depeche Mode, Sade, Duran Duran, Pet Shop Boys and Tina Turner to iconic MTV-era gems from Billy Idol, Eurythmics, U2, Janet Jackson, Prince and many more.
It also features rarely seen archive television footage from the BBC vaults, including Terry Wogan interviewing Grace Jones, Bruce Springsteen on the Old Grey Whistle Test and Adam Ant performing his own stunts in a behind-the-scenes look at the making of the Prince Charming video.

Millions know their voices, but no one knows their names. In his compelling film, award-winning director Morgan Neville shines a spotlight on the untold true story of the backup singers behind some of the greatest musical legends of the 21st century.
Triumphant and heartbreaking in equal measure, the documentary is both a tribute to the unsung voices who brought shape and style to popular music and a reflection on the conflicts, sacrifices and rewards of a career spent harmonizing with others. These gifted artists span a range of styles, genres and eras of popular music, but each has a uniquely fascinating and personal story to share of life spent in the shadows of superstardom.
Along with rare archival footage and a peerless soundtrack, 20 Feet from Stardom boasts intimate interviews with Bruce Springsteen, Stevie Wonder, Mick Jagger and Sting to name just a few. However, these world-famous figures take a backseat to the diverse array of backup singers whose lives and stories take center stage in the film.

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?

Tyson describes the discovery of cosmic rays by Victor Hess through high-altitude balloon trips. Swiss Astronomer Fritz Zwicky, in studying supernovae, postulated that these cosmic rays originated from these events instead of electromagnetic radiation. Also tells how Vera Rubin observed that the rotation of stars at the edges of observable galaxies did not follow expected rotational behavior leading to consider the existence of dark matter. This further led to the discovery of dark energy to account for the increasing rate of expansion of the universe. Tyson then describes the interstellar travel of the two Voyager probes. Tyson tells the Carl Sagan's role in the Voyager program, including creating the Voyager Golden Record to encapsulate humanity and Earth's position in the universe. Tyson concludes the series by emphasizing Sagan's message on the human condition in the vastness of the cosmos, and to encourage viewers to continue to explore and discover what else the universe has to offer.

In 2011, a Social Security lawyer named Eric C. Conn and a judge named David Daugherty were investigated for committing massive fraud over many years. Conn figured out that he would get paid a hefty retainer for every Social Security disability payment he managed to get approved, so he and Daugherty (who need quick cash to pay for his daughter’s upcoming narcotics trial – which presumably meant bribing an awful lot of people) came to an arrangement.
In the second episode, Investigators starts to collect evidence against Eric and Judge Daugherty. The whistle-blowers are pressured.
