Excitement and anticipation surrounds the 1986 Space Shuttle Challenger launch from Kennedy Space Center in Florida, U.S. This momentous endeavour would mark the first time that any civilian has been flown into space. On 28 January, 1986, school children and others watch eagerly on the ground and on television, as school teacher Christa McAuliffe prepares to become the first civilian to join the astronauts. At 11:38 AM, Space Shuttle Challenger lifts off, barrelling towards the atmosphere. However, a mere 73 seconds later, onlookers and the nation watch in horror when the shuttle is suddenly engulfed in flames and breaks apart in the sky. A full-scale enquiry of the crash is launched with NASA officials searching for clues to the shuttle's explosion, desperate to answer the most agonizing question: could this tragedy have been prevented?

The tranquillity of Montserrat, an island paradise in the Caribbean, is shattered in 1995 when the Soufriere Hills erupt for the first time in recorded history. The eruption takes the population of Montserrat by surprise. Scientists flock to the island and closely monitor the volcano over the next two years. Evacuations take place and an exclusion zone is mapped out. Then at 12:45pm on June 25th 1997 two years after the first eruption a massive tremor rocks the mountain. A plume of hot ash and steam soon spews into the air; reaching 45,000 feet in a matter of minutes and shrouding half the island in darkness. There follows 25 minutes of violent activity. When the ash finally settles many hours later, a scene of total devastation is revealed; many villages are buried and 19 people are dead. Many others are lucky to be alive. Montserrat is scandalised by the deaths and an investigation gets underway to discover how and why the deaths occurred.

The 1972 Munich Olympics holds significant promise, offering a chance to showcase a new Germany to a post-WWII world. However, this hopeful beginning meets a tragic end on September 5 at just after 4:00 AM when Palestinian terrorists kill two Israeli athletes and capture 9 others. As police struggle to handle the crisis, the terrorists anticipate their every move. By 1:30 AM on 6 September, the fighting finally stops, and all of the athletes, five terrorists and one German police officer are dead. With the circumstances behind the police's actions shrouded in mystery, one athlete's wife vows to uncover the truth. An anonymous source begins sending her copies of a classified German report investigating the police protocol. With the help of a hostage crisis expert who analyzes more than 3,000 files, the pieces of the puzzle begin to fit together. Supplemented by expert testimony, eye-witness and family member interviews, this gripping one-hour recount answers the most critical questions: How did the terrorists break into the Olympic village; how did the police's rescue plot go so terribly wrong; and how could this have been prevented?

Yiwu- the world's largest small commodities market. In 2014, as part of China's Belt and Road Initiative, the city became home to a new freight train network to Europe. Today, it takes only 16 days to reach Madrid on the longest freight train route in the world as compared to over a year on the ancient silk road 2000 years ago. Historian Sam Willis teams up with journalist Li Qiuyuan to dig into Yiwu's trading past and explore how this modern-day rail link is changing how China trades with the west.

2000 years ago, in the time of the ancient Silk Road, the journey between China, Central Asia and Europe often took an entire year. Today, goods can be transported overland in just 14 days thanks to the world's longest rail service, a 13,000 KM route that connects China and Europe. Now, with ancient connections being revived for the 21st century, historian Sam Willis and journalist Li Qiuyuan travel to Chengdu, to explore how a new era of trade is shaping the city.

Before humans ruled the world, planet Earth was a land of giants. But of all the beasts that ever lived…which is the biggest? Now experts take us on a journey to uncover the top ten largest of their kind. From bugs the size of hawks, to snakes the size of buses, to sharks that could bite a truck in half, we count down from ten. We investigate the latest discoveries, explore remote sites and follow the science behind the mind-blowing size of these creatures. And using photo-real CGI and dramatic demonstrations we reveal the true scale and awesome abilities of these creatures.

Nāvējošais vulkāna izvirdums, kas 79. gadā mūsu ērā apraka Pompeju, prasīja vēl vienu upuri, proti, Herkulānu. Šī piejūras pilsēta, kas atradās tuvāk Vezuva krāterim, bija pārklāta ar piecas reizes biezāku pelnu kārtu nekā Pompeji, taču brīnumainā kārtā ir vēl labāk saglabājusies.
