The London Underground network carries up to 4 million passengers per day, yet few of them know just how haunted the tube really is. This hair-raising journey takes us through the graves, church crypts and plague pits that tube tunnels have disrupted. We hear the startling stories of the men and women who work one hundred and fifty feet below our capital’s pavements; we also scrutinise the network’s amazing architecture and exceptional engineering.

This remarkable programme enables us to survey one of the most familiar environments in London from a radical and chilling perspective. We hear the supernatural stories of London Underground staff members who man the echoing stations and tunnels at night, long after the commuters have disappeared. For the first time on camera, drivers and station staff discuss their unexplainable subterranean experiences, outlining the effect that the incidents have had on them.

The Bermuda Triangle is a region located in the western part of the North Atlantic Ocean in which a number of aircraft and surface vessels are alleged to have mysteriously disappeared in a manner that cannot be explained by human error, piracy, equipment failure, or natural disasters. Popular culture has attributed these disappearances to the paranormal, a suspension of the laws of physics, or activity by extraterrestrial beings.

While a substantial body of documentation reveals that a significant portion of the allegedly mysterious incidents have been inaccurately reported or embellished by later authors, claims by official agencies, stating that the number and nature of disappearances in the region is similar to that in any other area of ocean, have been directly challenged by the investigations of several private researchers.

The ancient Maya civilization of Central America left behind a riddle: an intricate and mysterious hieroglyphic script carved on stone monuments and painted on pottery and bark books. Because the invading Spanish suppressed nearly all knowledge of how the script worked, unlocking its meaning posed one of archaeology’s fiercest challenges, until now.

This documentary presents the epic inside story of how the decoding was done, told by the experts at the center of one of archaeology’s greatest detective stories. Cracking the Maya Code highlights the ingenious breakthroughs that opened the door to deciphering the elaborate and exotic script and finally cracked the code, unleashing a flood of dramatic new insights about the ancient civilization.

Documentary about the London Underground Map, the epitomy of London Transport’s modernist design, which showed relative positions of stations along the lines rather than exact geographical locations, to produce a highly usable schematic diagram that has hardly changed since its introduction.

Created in 1931 by Underground employee Henry Beck, the graphically revolutionary map has become an icon of both London and British design.

We’re inherently bad at making decisions. According to science, our decisions are based on oversimplification, laziness and prejudice. And that’s assuming that we haven’t already been hijacked by our surroundings or led astray by our subconscious.

Featuring exclusive footage of experiments that show how our choices can be confounded by temperature, warped by post-rationalisation and even manipulated by the future, the programme presents a guide to better decision making, and introduces you to mathematician Garth Sundem, who is convinced that conclusions can best be reached using simple maths and a pencil.
