Air and Space

After the British discover that Nazis are experimenting with an advanced supersonic rocket-powered aircraft, they commission engineers to take up the same challenge.

Teams vie to find any evidence that a hidden planet exists in the solar system.

Like any powerful technology, rockets are a double-edged sword: they will both take men to great new heights, and power some of the deadliest weapons ever created.

NASA has future plans to look at the sun and the deep oceans of icy moons.

Part 2/2. In September 1942, Luftwaffe bomber pilot Horst Goetz is on a mission to strike Britain from over 40,000 feet; one Royal Air Force officer -- flying in a modified Spitfire -- is Britain's hope against the attack.

Mars One aims to transport people to Mars by 2027; experts talk about the mission, investigate the risks and challenges and highlight the possibilities.

When Mars One invited citizens to journey to Mars, 200,000 people applied; the final 100 include a military jet pilot, an ER doctor and an IT consultant — all willing to leave their loved ones forever; they share a common dream and a willingness to endure isolation.

During World War II, the fastest British jets can reach 500 miles per hour; with the sound barrier at 720 miles per hour, the British leap to create a supersonic jet is an unprecedented challenge.

The research, sacrifice and innovation behind the Apollo moon landing on July 22, 1969.

Just as the Vietnam War is ending, another begins next door; a Khmer Rouge attack on U.S. interests in Cambodia leave American soldiers trapped in harm's way.

Exploring a supermassive black hole in the heart of our own Milky Way Galaxy.

From carrying atomic bombs over the North Pole to flying over live volcanoes as Sean Connery's body double, explore the life of Ken Wallis; the inventor's passion for aviation keeps him airborne even into his nineties.

Ex-CIA agent Ben Smith and a retired FBI officer journey through the jungles of Burma in search of a crashed WWII plane.

The Nazis seek to further their exploration of rocket power and create new aircraft that will give them dominance of the skies; Alexander Lippisch moves from designing gliders to the first rocket-powered production aircraft: the Komet.

The trek from Earth to Mars is fraught with difficulties, from surviving radiation en route to landing in a spacecraft not yet designed; from a greenhouse in Holland to a desert landscape in Iceland, scientists are using the Earth to test ways to keep a Mars settlement alive and well.

The Lockheed Constellation, affectionately known as the Connie, was one of the most elegant and aesthetically pleasing aircraft to ever take flight.

Scientists recount the challenges of developing the James Webb Space Telescope, the most expensive, largest and most advanced ever built.

Host Sean Riley charts a course into the wild blue yonder to look back at the original challenges of air travel and forecast what's next in aviation.

It was the thick of WWII and Allies needed a way to get behind enemy lines; it would take an advanced flying machine to get this job done, pushing the limits of rotary flight; see how a regular Jeep utility vehicle was transformed into the Flying Jeep.

The OSIRIS-REx team launches a spacecraft to an asteroid to collect a sample of Bennu.

A new breed of aviators is innovating new ways to fly from clean and green electric aircraft to autonomous sky taxis.

During World War I, several new innovations emerged on the battlefield and proved crucial to breaking the stalemate of trench warfare; high on the list was the tank and the airplane; almost as soon as those two inventions entered the war, military planners and engineers endeavor ways to combine the two and create a mega-weapon, The Flying Tank.

When it comes to space exploration, expect the unexpected. As OSIRIS-REx approached asteroid Bennu, scientists were surprised to find a loosely packed rubble pile. This week, we get a closer look at Bennu and the surprises it holds in store.
