Harrison Okene spent three days trapped in an air pocket in a sunken ship.

Harrison was the ship's cook, and he'd been in the bathroom when the tugboat he worked on had suddenly capsized in bad weather. The vessel sank 30 metres to the seabed, upside down, and Harrison was trapped inside.

Days passed, and up on the surface a mission was launched to recover the bodies of the tugboat's crew. Divers descended, but they never expected to find anyone alive.

In 1982, two Mississippi boys recreated a $22m film, shot-for-shot, on their pocket money.

Chris Strompolos and Eric Zala were aged 10 and 11. Their mission would take them seven years to complete, and it would push their friendship to the edge. There’d be amateur stunts, fires, visits to the emergency ward, production shut down by angry parents and many fallouts. It would swallow them whole.

But decades later a lost tape would be unearthed, bringing Eric and Chris back together for their final scene and face-to-face with one of their heroes.

How a jump changed daring parachutist Tony Osornio's life forever.

Tony was Mexico's best precision skydiver and the first woman to join her country's army. She says she "belonged to the skies", and became a member of an elite team of performance skydivers called the Crazy Birds. She was prepared to sacrifice everything for her love of parachuting - until a jump went badly wrong.

Tony Osornio would go to dangerous extremes to keep skydiving.

She was born into a conservative family, and decided to marry the first man who asked in order to escape the restrictions of home.

Her husband was a Mexican military officer with access to the planes used by elite paratroopers. With his help, Tony would sneak on board too, parachute strapped to her back. In love with jumping, she decided she needed to join the Mexican army herself, something no woman had done before.

By 1981, Pakistani-born immigrant Tariq Mehmood had endured years of violent racism in Britain. When he heard that gangs of white skinheads – with a history of attacking Asians – were coming to his home in Bradford, Tariq and his neighbours took desperate measures to defend their community. Underpinning their actions was the principle, “self-defence is no offence.” Tariq would end up being arrested, charged with conspiracy to make explosives, and facing life imprisonment. What followed was the landmark legal case of the Bradford 12.

Hand on the Sun, the novel that Tariq wrote in prison over 40 years ago, has been re-released with a new update.

As a Pakistani immigrant teenager in 1970s Britain, Tariq Mehmood endured homelessness and years of violent racism. He found shelter and wisdom in a library, and the strength to stand up to the racists. He co-founded the Asian Youth Movement, and their slogan “self-defence is no offence,” would galvanise an entire generation. But it’s a rationale that would see Tariq in court – facing life in prison – in the groundbreaking case of the Bradford 12.

Stany Nyandwi's rescued chimpanzees helped him through war and loneliness.

As a young boy Stany made money selling sugarcane and worked as a 'houseboy' for families in Burundi's capital city Bujumbura. But later, a job with rescued chimpanzees became about more than just money. When ethnic conflict in Burundi escalated into civil war, Stany fled to safety with the chimps who, with histories of their own, gave him companionship and a ticket to a future without war.

Stany is a chimp specialist and his behaviour should not be copied or emulated in any way.

He has co-written a book called The Chimpanzee Whisperer: A Life of Love and Loss, Compassion and Conservation.

The ship was running out of fuel, and starting to malfunction.
