This book is an overview of both the history of aliens and UFOs, as well as a review of hidden aerospace and propulsive technologies. Where did these technologies come from? And how have they developed in the intervening years? Also, I try to answer some questions of how likely some of these claims are - because some things having to do with UFOs and aliens are much more documented than others. There are also many alien-related and secret programs that most of you listeners may have never heard of. The most interesting ones are summarized here.

In this fascinating foray into the centuries-old relationship between science and military power, acclaimed astrophysicist Neil deGrasse Tyson and writer-researcher Avis Lang examine how the methods and tools of astrophysics have been enlisted in the service of war. "The overlap is strong, and the knowledge flows in both directions," say the authors, because astrophysicists and military planners care about many of the same things: multi-spectral detection, ranging, tracking, imaging, high ground, nuclear fusion, and access to space. Tyson and Lang call it a "curiously complicit" alliance.

Discover the definitive history of DARPA, the Defense Advanced Research Project Agency, in this Pulitzer Prize finalist from the author of the New York Times best seller Area 51. No one has ever written the history of the Defense Department's most secret, most powerful, and most controversial military science R&D agency. In the first-ever history about the organization, New York Times best-selling author Annie Jacobsen draws on inside sources, exclusive interviews, private documents, and declassified memos to paint a picture of DARPA, or "the Pentagon's brain".

It is the most famous military installation in the world. And it doesn't exist. Located a mere s75 miles outside of Las Vegas in Nevada's desert, the base has never been acknowledged by the US government - but Area 51 has captivated imaginations for decades. Annie Jacobsen had exclusive access to 19 men who served the base proudly and secretly for decades and are now aged 75-92, and unprecedented access to 55 additional military and intelligence personnel, scientists, pilots, and engineers linked to the secret base, 32 of whom lived and worked there for extended periods.

Now on audio! The best-selling exposé that ends the decades-old controversy surrounding the infamous and mysterious crash of an unidentified aircraft at Roswell, New Mexico, in 1947.

Adapted from Decoded, Meltzer's hit show on the History network, History Decoded explores many fascinating and unexplained questions. Is Fort Knox empty? Why was Hitler so intent on capturing the Roman "Spear of Destiny"? What's the government hiding in Area 51? Where did the Confederacy's $19 million in gold and silver go at the end of the Civil War? Did Lee Harvey Oswald really act alone?

As the 50th anniversary of the first lunar landing approaches, the award-winning historian and perennial New York Times best-selling author takes a fresh look at the space program, President John F. Kennedy’s inspiring challenge, and America’s race to the moon.

Award-winning investigative journalist Ross Coulthart has been intrigued by UFOs since mysterious glowing lights were reported near New Zealand's Kaikoura mountains when he was a teenager. The 1978 sighting is just one of thousands since the 1940s, and yet research into UFOs is still seen as the realm of crackpots and conspiracy theorists.

In the classic Our Haunted Planet, John A. Keel brings into chilling focus strange truths about the Earth and its mysterious inhabitants. Could an unseen, prehuman race have taken careful measures to remain hidden from surface dwellers? Are they still watching us from their secret hiding places, manipulating and misleading us, using us for their own entertainment, and controlling our actions?

The biggest lie in history is about to be shattered. UFOs are real. In late June of 1947, three extraterrestrial craft were downed outside Roswell Air Force Base. Many more followed, revealing dozens of ET species and a Rosetta Stone to a new physics, an energy generation and propulsion system responsible for interstellar space travel. This new system could have easily replaced oil, gas, coal, and nuclear plants - and with them, the entire geopolitical and economic order on our planet. But a cabal of bankers, the military-industrial complex, and Big Oil stopped it.

After the Soviet Union proved to the United States that it possessed an operational intercontinental ballistic missile with the launch of Sputnik in October 1957, the world watched anxiously as the two superpowers engaged in a game of nuclear one-upmanship. Amid this rising tension, eccentric physicist Nicholas Christofilos brought forth an outlandish, albeit ingenious, idea to defend the US from a Soviet attack: detonating nuclear warheads in space to create an artificial radiation belt that would fry incoming ICBMs. Known as Operation Argus, this plan is the most secret and riskiest experiment in history, and classified details of these nuclear tests have been long obscured.

How much should you pay for a return trip to the moon? How are Winnie the Pooh and the artificial heart related? Did teenagers exist before 1950? If not, who invented them? James May's 20th Century answers all these questions and more.

Chronicling the history of the Reptilian Empire's influence on Earth and their conquest of 21 star systems, Kasten reveals how the human race is enmeshed in a skillfully concealed plot to enslave humanity and exploit our planet's physical and biological resources. Revealing Hitler's pact with extraterrestrials and the Reptilian influence on the Nazi state, he shares new documents that disclose the rescue and rehabilitation of Nazi war criminals to assist in the Cold War, which then corrupted many US government institutions.

In 1945, the Japanese cities of Hiroshima and Nagasaki became the first and last victims of the atom bomb, the most destructive man-made force our planet has ever known. Or were they just the latest in a long line of Armageddon-level events? Is it possible that our civilization is, in reality, just one of many? Did previous cultures blossom, develop, and thrive only to destroy themselves, tens or hundreds of thousands of years ago, with the same atomic technology?

Over the last 50 years, humanity has developed an extraordinary shared utility: the global positioning system. Omnipresent, free, and available to all, GPS powers everything from your phone to the Internet to the Mars Rover. Greg Milner tells the sweeping story of GPS, from its conceptual origins as a bomb guidance system to its present ubiquity.
