Shawn Henry, a former FBI official, investigates shocking evidence supporting the idea that Amelia survived her last flight, including a photograph purporting to show herself and Fred to be still alive in the Marshall Islands after the disappearance. Having crashed on the islands, it is said that she was then caught by the Japanese military and died in their custody.

The documentary presents evidence that has been verified by the reputable professionals. This includes plane parts discovered on the Marshall Islands that are of the same aircraft type Amelia was flying, and an interview with an eyewitness who claims to have seen Amelia and Fred after they crashed.

The documentary takes a look at a newer hypothesis about a destructive fire below the Titanic’s deck and how it may have caused the ship to sink. The fire was originally downplayed in terms of its impact on the ship’s fate. The film provides an insight into the ‘perfect storm’ of factors that came about to cause the ship to sink, according to the proposed hypothesis.

Using newly declassified FBI files from 1947, a team of specialists headed by former CIA operative Bob Baer follow leads to investigate Nazi artefacts and unearth undiscovered Nazi military equipment. They also uncover supposed Nazi hideouts and escape networks. The goal is to determine whether the notorious dictator managed to survive the war and pull-off one of the world’s greatest disappearing acts.

The series appeals to history and geography buffs alike as it examines sites across the globe in effort to find the undiscovered remains of Adolf Hitler.

Where is Flight MH370 reveals how the plane moved into an aviation radar blind spot, investigators’ beliefs regarding the last moments of the flight, and how the suspected crash site is still to be searched. It also discusses the technologies that are being adopted and developed in order to avoid repeat disappearances, such as black box streaming and enhanced air traffic surveillance to eliminate blind spots. The search for the plane has intensified with the aid of deep-sea sonar equipment to explore an 60,000 square kilometer area of the ocean.

The film presents the case for having discovered the mythical city. Hartford University’s Professor Freund leads the investigation after a strong belief that the city was demolished by a massive tsunami in 9,000 BC. Inspired by finding a stele in Cadiz, Spain, which he believes may have stood at Atlantis’s entrance, his search has focussed on nearby marshlands to detect even the most remote of traces of the city.

While Finding Atlantis presents Spain’s waterways as Atlantis’ graveyard, the idea that it resides in Spain is only the newest theory surrounding its location. Previously, American oceanographers believed the city was near Cyprus and before that, it was considered to reside in the Mediterranean, the Central Americas and even the Antarctic.

While a number of topics, conspiracies, and mythologies are tackled, each episode is based around what the “ancient astronaut theorists” theorise actually happened in history. The base assumption around each episode is that extra-terrestrials gave ancient mankind the knowledge to accomplish major feats in architecture and technology. Ancient Aliens has been criticised for being pseudo-scientific, but that certainly does not mean it cannot make viewers question the world around them.

The Revelation of the Pyramids then goes into comparisons between Giza’s pyramids and those of other regions like China, Easter Island and the various native cultures of the Americas. The film posits that Giza’s construction implies that Egyptians would have to have been incredibly advanced mathematicians, using equations centuries before they were discovered by the rest of the world. It therefore draws the conclusion that the pyramids were not built by Egyptians, but by a significantly older civilisation that has long-since faded away into the mists of time.

Likely this was a tale used to dissuade Staten Island kids from exploring what remained of the mental institution, but the documentary delves deeper into this legend by linking it to a real life figure of malevolence. Shifting from childhood tall tales to a harrowing reality, Zeman and Brancaccio explore the kidnapping of a 13 year old girl with Down’s Syndrome. Their investigation of this crime that made Cropsey feel real all those years ago brings them to a drifter who might be linked to the disappearances of other Staten Island kids.

The documentary shows glimpses of Masonic symbols and iconography, the inner workings of a lodge, and discusses the order’s history and philosophy as told by masons themselves. It also features age-old rituals and traditions, interviews with a 33rd degree Master Mason, and a detailed look at an initiation ceremony.
