In 1961, Viv Nicholson became a household name in Britain when she and her husband scooped a massive win on the football pools.

Viv Nicholson's story later became a successful West End musical and stage play. Simon Watts talks to her son, Howard Nicholson, author of "You Don't Know Viv".PHOTO: Howard and Viv Nicholson (left and centre) with British entertainer Bruce Forsyth (Getty Images)

How two pilots, Dick Rutan and Jeana Yeager, became the first to fly non-stop around the world without refuelling in December 1986. Their experimental aircraft was designed by Dick's brother, Burt Rutan. It had to be incredibly light to carry the huge weight of fuel required. But that meant the plane was vulnerable to breaking up in turbulence. Dick Rutan and Jeana Yeager endured storms and equipment malfunctions to set the world record. They spent 9 days, 3 minutes and 44 seconds in the air. Alex Last speaks to Dick Rutan about their achievement. Photo: The Voyager aircraft designed by Burt Rutan (NASA).

When Bhimrao Ramji Ambedkar was a schoolboy, he was not allowed to drink from the same tap as his fellow students because he was a member of what was then known as an "untouchable" caste. But he went on to become a prominent leader in the campaign for Indian independence and oversaw the writing of the Indian constitution - which made the idea of "untouchability" illegal. A hero to many, he died in December 1956.Lucy Burns hears recordings of BR Ambedkar from the BBC archives and speaks to biographer Ananya Vajpeyi.Picture: A member of the Indian Congress Party places flowers on a statue of BR Ambedkar to mark the 122nd anniversary of his birth in Amritsar on April 14, 2013 (NARINDER NANU/AFP/Getty Images)

A controversial Islamic movement brought a brief moment of peace to Mogadishu in 2006 after years of war. The Islamic Courts Union (ICU) came to power after defeating rapacious American-backed warlords. They had no unified ideology or leadership. Some were moderates, some were hardline Islamists. But they brought law and order to the capital unseen since civil war began in 1991. But their rule would only last for six months and from the ashes would emerge the radical militant group Al-Shabab.Photo: Somalia's Supreme Council of Islamic Courts (SCIC) militia display their flag in front of Hotel Ramadan, in Mogadishu, 15, July 2006 (STRINGER/AFP/Getty Images)

Thousands died as a thick polluted fog engulfed London in 1952. People with respiratory and cardiovascular conditions were most at risk. The smog was a combination of pollution from millions of coal home fires and freezing fog. Unusual atmospheric conditions trapped the pall over the city for four days.

Alex Last speaks to Dr Brian Commins, who worked for the Medical Research Council's Air Pollution Unit set up at St. Bartholomew's hospital in London in the 1950s.

The Russian Revolution of 1917 led not just to huge political and social change, but to a new artistic freedom. Russian avant-garde artists like Malevich, Kandinsky and Chagall flourished in the immediate aftermath of the revolution. One of their greatest supporters was art curator Nikolai Punin. Louise Hidalgo has been talking to Punin's granddaughter, Anna Kaminskaia, about how that freedom was gradually replaced with censorship and repression, and her grandfather ended his life in the Gulag.Picture: 1920 painting by Boris Mikhailovich Kustodiev (1878-1927), Bolshevik (oil on canvas), Tretyakov Gallery, Moscow, Russia

In December 1917 Finland proclaimed its independence. For many centuries it had been controlled by its powerful neighbours, Sweden and Russia. As World War One raged across Europe and Russia was embroiled in its own revolution, Finnish intellectuals took the opportunity to push for their own state. But many ordinary people were more concerned with dire food shortages and the chaos caused by conflict. Olga Smirnova hears memories of that time.(Photo: 1917: A Communist base burning during the Finnish civil war.

In 1967 the British withdrawal from their colony of Aden led to the creation of the People's Republic of South Yemen. Britain had colonised the port city in 1839. Aden had been at the centre of the British colonial trading system and had been one of the busiest ports in the world. The handover has been described as one of the most chaotic in British colonial history. Farhana Haider has been speaking to the former British diplomat, Oliver Miles and to Ghassan Luqman who says the scars of Britain's quick withdrawal are still being felt in Yemen today.Photo: Aden 1967 Copyright: Alamy.
