2. Brazil's Roswell

It's all hush-hush as we track a secretive global paper trail, delving into government plans on how to deal with other-planet visitors. Searching historical records, we find that protocols are in place--from the U.S. military's JANAP-146 reporting requirements to France's Cometa files, from Chapter 13 of the FEMA Fire Officer's Guide to Disaster Control titled "Enemy Attack and UFO Potential", to a now-repealed federal law titled "Extraterrestrial Exposure".

4. UFOs: Then and Now - Aliens and Contact

Investigation into the 1991 mass UFO sighting over Mexico City during a solar eclipse and other sightings as possible examples of alien contact with the inhabitants of planet Earth.

5. Deep Sea UFOs: Red Alert

The puzzling formations known as crop circles have appeared worldwide throughout history. In the Middle Ages, they were called "witch" or "pixie" circles, and a 1678 woodcut, the "Mowing Devil", depicts one thought to be Satan's work. But in the 1980s, the phenomenon escalated, with dozens of crop circles popping up in England and other countries. When two Englishmen claimed they had perpetrated the hoax, many felt the riddle was solved. And yet, more have materialized. We explore the mystery.

8. Majestic Twelve UFO Cover-Up

In an investigation of some of the most puzzling UFO sightings in Soviet history, we uncover the work of an underground network of believers and reveal a clandestine 13-year government investigation of UFOs. Many Russian UFO enthusiasts believe that proof of alien encounters exists--but it's being hidden from them! We also meet George Knapp, an American broadcast journalist who traveled to Russia in the early 1990s and believes there's a treasure trove of KGB UFO files that remain top-secret.

10. Alien Engineering Part 1

UFO Files examines the most debatable aspect of alien contact--human abduction! From the first recorded case, the 1961 kidnapping of Betty and Barney Hill, to the 1976 Allagash Incident, when four friends were whisked away while on a camping trip, we hear firsthand from participants and a neuroscientist, who offers more earthbound solutions.

12. UFO Hunters

They look to the stars, to Earth, and within the human body. They are the UFO research elite that seeks answers to the mysteries of the UFO phenomenon. Their determination, attitude, and methodologies stand strong against ridicule and disbelief. In the end, UFO hunters exhibit scientific evidence that pushes the boundary of modern-day thinking. At annual conferences, they share findings and are often stunned by the commonality of their cases. Follow UFO hunters as they search for UFOs and investigate crash sites. Their hunts for physical evidence of UFOs and alien life forms sometimes end up as global wild goose chases, but there are other times, when what they find is just too intriguing....and might just prove that it is possible that we are not alone in the universe.

The phenomenon of alien abduction is reviewed. Hypnotic regression is conducted and an alleged implant is removed.

14. China's Roswell

Since the 1960s, thousands of UFO landings, flyovers and collisions have left scientific evidence behind for study. These events have become known in the field of UFOlogy as the "trace cases." There are over 3,000 documented UFO physical trace cases and they have occurred in over 90 countries around the world. From impressions in the dirt, burned or broken vegetation and trees to scientific abnormalities that have yet to be explained, trace cases offer up some of the most convincing evidence of the UFO reality.

17. Hangar 18: The UFO Warehouse

What happens when a UFO crashes? Some experts claim that the UFO wreckage and even the pilots are transported to a top-secret facility in Dayton, Ohio called "Hangar 18" located on Wright Patterson Air Force Base. Declassified Government documents prove that the "disk" from the famous Roswell event and fragments of other mysterious crashes were shipped to Wright Patterson. Hear stories involving elected officials, UFO researchers, and former base employees, some of whom are going on the record regarding "Hangar 18." They spin a tale of flying saucer debris, alien bodies, cryogenic chambers and a vast underground network that may hold the secrets to the UFO mystery. Is there a conspiracy to hide UFO evidence from the highest branches in the U.S. Government, or is it all just a myth?

32. The Day After Roswell

Delve into the aftermath and repercussions of the 1947 Roswell incident, when many believe an alien spacecraft crashed in New Mexico. Based on The Day after Roswell by Lt. Col. Philip J. Corso and William Birnes, we explore if technologies like the laser, fiber optics, the integrated circuit, super-strong fibers, and night vision were developed with the aid of aliens. Career officer Corso claims his first alien encounter came on July 6, `47, while on late-night security rounds at Ft. Riley, Kansas, where he saw bodies of EBEs (extraterrestrial biological entities) inside shipping crates. In 1961, as Chief of Foreign Technology in the Army's department of Research and Development, his job included analyzing alien technology from Roswell, then introducing it into America's technological mainstream--thus, reverse-engineering alien artifacts. And we talk to many scientists involved at the time, who credit hard work, not alien contact, with these technological advances.
