Clay is the clear favourite, but the showdown will be remembered as one of boxing history's most shocking battles, changing both men forever and showing what it really means to win.

Evel Knievel, the world-famous daredevil, is planning his greatest ever stunt. In 1974, he wants to leap over Snake River Canyon in Idaho. The chasm is almost a third of a mile wide, much bigger than any jump he's done before. To make it work, he'll need a custom-made rocket-powered "Skycycle," TV camera crews and - most importantly - a very positive attitude.

This is a special crossover episode with Business History.
John DeLorean was a visionary who wanted to create a futuristic new sports car - a stainless steel marvel with distinctive gull-wing doors. The British Government agreed to finance the project, provided he built his factory in a troubled part of Northern Ireland. Production stumbled, sales fizzled and DeLorean liked to fiddle with the numbers. As the company approached ruin, a neighbour offered DeLorean a lifeline, if he'd only come in on a cocaine deal.

Windscale is supposed to be Britain's big leap into the nuclear age, bringing science fiction to life in 1950s Northern England. But in the race to catch up with America's nuclear program, scientists are tinkering with forces they don't fully understand. When the reactor catches fire, no-one knows how bad it could be, or how to put it out. As the reactor workers scramble to save lives, other eyes on Windscale are much more concerned with containing the political fallout and burying the truth.

If you tuned in to late-night WOR radio in 1950s New York, you'd enter the secret world of Jean Shepherd. Shepherd's nonconformist style, off-beat humor and love of pranks gathered a small but loyal following. These "Night People" loved being in on the joke, while the oblivious "Day People" were often the butt of it. Shepherd's show is long gone, but his spirit lives on in corners of the internet. Today, though, Night People go by a different name.

In Tudor England, the line between mathematics and the mystic arts is vanishingly thin. Straddling both worlds is John Dee, a brilliant scholar and astrologer whose intellect grants him access to the highest circles of power. Dee navigates the politics of the court by making bold prophecies, which win him royal favour. But even correct predictions may come with a price - and laying claim to the future is a dangerous game.

Mike Lynch was often lauded as Britain's answer to Bill Gates. Born into a working-class family, Lynch's incredible intellect and passion for computers led him to become a billionaire tech entrepreneur. But behind the scenes, Lynch was a bully who couldn't bear criticism and was prone to creative accounting. When computer giant Hewlett Packard bought his company, Autonomy, it triggered one of the biggest fraud scandals in Silicon Valley history. Tim talks to Katie Prescott, Technology Business Editor at The Times and author of the book The Curious Case of Mike Lynch, about the lessons we can take from a story no one could have predicted.

Until the 1960s, it was deemed too "dangerous" for women athletes to run distances longer than 200m - and a marathon would kill them, or leave them unable to have children. Rubbish, of course. But when Kathrine Switzer signed up for the 1967 Boston Marathon, it wasn't the distance that bothered her - it was the enraged race director trying to assault her.
Thanks to pioneers like Kathrine, women have made huge strides in long distance running - and are now challenging the times of men in the very races they were banned from for so very long.
