If ancient aliens visited Earth in the remote past, could they have given us advanced technology, past down through human history? And could this technology have helped the Third Reich build mysterious weapons and crafts far beyond the limits of 20th century science? During World War II, there were reports that the Germans built an operational flying saucer, known as the Hanebu, which was said to use mythical technology found in ancient Indian texts. Another craft was rumored to have been constructed with the help of psychics and mediums who claimed to have received detailed blueprints from extraterrestrial beings. Is it possible Hitler's quest for world domination was aided and abetted by ancient extraterrestrial technology that was rediscovered? And could the allegedly rebuilt alien devices developed in Germany have played a role in America's ability to land a man on the moon? TVPG VL | CC Show Site

NASA scientists, former astronauts and secret government files all point to the conclusion that there has been contact with extraterrestrial life in the past.

When Scott Wolter began investigating mysterious artifacts, he started to notice one unique symbol appeared on many of them. The symbol, now known as the "Hooked X", baffled researchers who couldn't make sense of it. As Scott's investigation into the origins of the symbol unfolds, he realizes its use is unique to just two notoriously secret groups--the Knights Templar and their modern day brethren, the Freemasons. Used in secret codes, cryptic ciphers and even the alleged tomb of Jesus himself, the symbol could be the key to understanding two of the biggest mysteries of all time--exactly what the Holy Grail is, and where it's hidden today.

The end of the Civil War allows Mankind to go into overdrive. This is an age of innovation, transformation and mass production. People believe that "Anything, everything, is possible." Japan goes from feudal society to industrial superpower within 50 years. But progress has its dark side. The demand for rubber devastates Africa. And the desire to build bigger, faster, better leads to a titanic disaster...Mankind takes on godlike powers: to feed billions of people, reshape the landscape, re-engineer the human body. The greatest power of all was unleashed over Hiroshima on August 6th 1945. Since entering the Atomic Age we've been living between eternity and oblivion. But at the same time, we've become more connected as a species. 100,000 years ago there were a few thousand hunter-gatherers on the African savannah. Today there are 7 billion of us in every corner of the globe. It's been an amazing journey. (2 hours.) TVPG VL | CC Show Site

The Alaska Ocean is the largest factory-fishing boat in the US fleet. The crew's mission: hunt down, catch and process 300 tons of Alaskan Pollock each day on the unforgiving waters of the Bering Sea. We travel with them on the last voyage of a long and grueling season. The crew reveals the inner workings of one of the most sophisticated and complex vessels afloat. It is half fishing boat, half floating factory, processing and flash freezing Alaskan Pollock as fast as its crew can catch it. To meet their seasonal quota of Pollock, the crew must overcome obstacles of weather, mechanical dangers aboard the sea-tossed ship and the wiliness of the fish themselves. Captain Scott Symonds takes us inside the amazing ultra-modern world of high stakes commercial fishing where a wrong decision on his part can cost not just the season's catch, but also the lives of his crew.

In 1975, Travis Walton claims to have been abducted and taken aboard a space ship inhabited by extraterrestrial beings. Several people witnessed his encounter and nearly 40 years later Walton's story of alien abduction, missing time and mind-telepathy manipulation has not wavered. But researchers say that abductions are not a modern phenomenon. The Hebrew Bible is filled with stories of abductions by otherworldly beings. Jonah, Moses, Ezekiel and Enoch all depict what can best be described as physically being taken to other dimensions and then returned. Is it possible that extraterrestrial beings have been abducting humans for thousands of years and if so, might there be an alien agenda behind the phenomena? TVPG VL | CC Show Site

A look at the storied and strange history of marijuana in America and how it has been front and center in the war on drugs. While many in the general public think of marijuana as the "safe drug," the DEA has referred to it as a "gateway" drug that can open the door to the use of stronger substances. This illustrates the paradox of marijuana, which is underscored by the fact that while the U.S. has spent over $100 billion dollars to fight its import, sale, and distribution, 14 states including New Jersey and Michigan have legalized it for medicinal purposes. Additional states are set to make it legal for the same purposes. This special will examine the changing social and legal landscapes of marijuana and its history in a fresh and compelling way.
