In 2006, hundreds of thousands of school children in Chile took over their schools and marched in the streets, in a protest about inequality in education.

It was known as the "Penguin Revolution" because of their black and white school uniforms.

The students were demanding good quality education for all children, regardless of whether they were rich or poor.

Grace Livingstone speaks to Karina Delfino, who was a 16-year-old school girl and one of the leaders of the movement.

On 27 January 1945, prisoners at the Nazis’ largest death camp were freed by the Soviet Union’s Red Army.

General Vasily Petrenko commanded one of the four units that liberated Auschwitz.

The Nazis murdered 1.1 million people at Auschwitz-Birkenau between 1941 and 1945. Almost a million were Jews, 70,000 were Polish prisoners, 21,000 Roma, 15,000 Soviet prisoners of war and an unknown number of gay men.

It was one of six death camps the Nazis built in occupied Poland in 1942, and it was by far the biggest.

Vicky Farncombe produced this episode using an interview General Vasily Petrenko gave to the BBC’s Russian Service in 2001. He died in 2003.

On 28 January 1986, a space shuttle launch went wrong.

Six astronauts and a teacher, Christa McAuliffe, were killed.

In the early hours of 30 April, 1943, one of the most audacious hoaxes of World War Two has just got underway. Its code-name - Operation Mincemeat.

The body of a British naval officer, Major William Martin, has been washed up on a Spanish beach. The dead man is carrying top-secret papers revealing details of a planned Allied invasion, and it’s not long before they fall into enemy hands.

But the plans are false and Major Martin doesn’t exist.

In a daring mission, British naval intelligence has requisitioned a corpse and dressed him in uniform to plant fake information. It works.

But for decades, no-one knew the real name of the man who’d played the biggest part: Major William Martin.

Enter Roger Morgan, an amateur historian. He tells Jane Wilkinson how Operation Mincemeat unfolded and how he uncovered the major’s true identity.

In May 1986, a new airport opened in Knock in the west of Ireland. It was the dream of an Irish priest, Monsignor James Horan, who raised millions to have it built.

The location for the airport seemed impossible – set in the boggy, foggy hills of rural County Mayo.

However, Knock attracts more than a million pilgrims every year, who come to visit the supposed site of an apparition by the Virgin Mary and other saints.

So, Horan convinced politicians that this remote western landscape could host a gateway to the world, and service the pilgrims who come to visit the shrine of Knock.

Pearce Concannon was working at the local Knock Shrine when the airport opened and remembers when Horan asked him to quit his job and become a firefighter at his new airport. He speaks to Colm Flynn.

If journalism is the first draft of history, what happens if that draft turns out to be flawed? The History Bureau revisits the defining stories of our times with the reporters who first covered them. What did they get right first time around? And, in the chaos and confusion of unfolding events, what did they miss?

Season 1: Putin and the Apartment Bombs. In September 1999, just weeks after a 46-year-old Vladimir Putin became Prime Minister, four bombs blew up four apartment buildings across Russia, killing hundreds of people while they slept. The attacks plunged the country into panic. Families fled their homes. Residents patrolled their blocks around the clock. An entire nation paralyzed by fear. But who did it? It's a mystery that has fuelled some chilling theories. The government blamed Chechen militants. Many reporters agreed. But then the whispers started. Was something even more sinister going on?

If you're in the UK, listen first to The History Bureau on BBC Sounds - or elsewhere in the world, listen on BBC.com or wherever you get your podcasts.

In 2005, a new show was launched on television in Afghanistan to find new musical talent – it was called Afghan Star and was inspired by formats like American Idol and the X-Factor.

The programme came after the music industry in Afghanistan had been decimated under the Taliban between 1996 and 2001.

Music has been culturally important in Afghan history, however, playing music and musical instruments had been banned whilst the Taliban were in power.

Jahid Mohseni was the development producer for Afghan Star, he has been speaking to Tim O’Callaghan.
