The asteroid that killed the dinosaurs
65 million years ago an asteroid hit the earth, causing the extinction of the dinosaurs along with three quarters of all species on earth at the time. The crater where it hit was discovered on the Yucatan peninsula in 1978 during a geological survey for the Mexican state oil company Pemex. It was named Chicxulub.Lucy Burns speaks to Glen Penfield, who first identified the crater, and Alan Hildebrand, whose research confirmed the discovery.Image: NASA high resolution topographical map of the Yucatan Peninsula created with data collected in the Shuttle Radar Topography Mission and released on March 7, 2003 in Washington, D.C.

Walking the Great Wall of China
It took 508 days for three friends to complete the first trek along the entire length of the ancient structure, well over 8000 kms. They began in May 1984 and finally reached their destination at the Jiayu Pass on September 24th 1985, having documented the condition of the wall every step of the way. The three men became national heroes as the press followed their progress. Yaohui Dong spoke to Rebecca Kesby in 2017 about what inspired him to make the journey. This programme is a rebroadcast.(PHOTO: Yaohui Dong, Wu Deyu and Zhang Yuanhua. Courtesy of Yaohui Dong)

Hitler's stolen children
During the Second World War Nazi officials searched for blonde blue-eyed children in the countries they had occupied. The children were removed from their families as part of a plan to build an Aryan master race. Ingrid Von Oelhafen grew up in Germany and only found out in her 50's that she had been born to Slovenian parents. At nine months old she was taken away and sent to a 'Lebensborn' children's home.

China's One Child policy
The Chinese Communist Party started ruthlessly enforcing birth control in the early 1980s. People with more than one child faced fines, or lost their jobs, or had children forcibly adopted. Yashan Zhao has been speaking to Zhou Guanghong who experienced the policy first-hand, both as a father and as a birth control official.Photo: a propaganda poster extolling the virtues of China's "One Child Family" policy.

The final days of Sri Lanka's civil war
In May 2009 the Sri Lankan army finally crushed the Tamil Tiger rebels, ending 25 years of bloody civil war. In the final weeks of the conflict, thousands of civilians were trapped alongside the rebels under heavy shelling as the government forces closed in. Journalists and aid workers were prevented from reaching the war zone. Mike Lanchin has been hearing from one Tamil woman trapped in the siege zone, and from the former UN spokesman in Sri Lanka, Gordon Weiss, who watched on from the capital Colombo as the fighting came to an end.Photo: Tamil civilians standing on the roadside after crossing to a government-controlled area 2kms from the front-line (Getty Images)

Predicting the financial crash
In the early 2000s, a handful of experts warned that the world was sleep-walking towards a financial crisis. Among them were South-African born political economist Ann Pettifor and the IMF's chief economist at the time, Raghu Rajan. But their warnings were ignored, and instead in 2008 the world plunged into the worst financial crash since the Great Depression, whose shadow still hangs over our politics. Louise Hidalgo has been talking to the Cassandras of the crash.Picture: Traders at the New York Stock Exchange watch as the Dow Jones share index plunges following the collapse of Lehman Brothers in September 2008 (Credit: Spencer Platt/Getty Images)
