August 6th 1945 marked the start of a terrifying new episode in human history. This documentary marks the 70th anniversary of the day when the world's first atomic bomb was dropped on the Japanese city of Hiroshima by a Boeing B-29 USAF Superfortress bomber, nicknamed Enola Gay after the pilot's mother". Up to 80,000 people - 30 per cent of the population - were killed by the blast and resulting firestorm and over 70,000 were injured. This documentary gives a minute-by-minute account of what happened on that fateful day, through the testimony of people who were there and rarely-seen archive footage from the time. Made on location in Hiroshima and the USA, it features unique interviews with eyewitnesses who have seldom, if ever, spoken about the experience. Several of them are no longer alive, they include the last surviving member of the crew of the Enola Gay - navigator Dutch Van Kirk who died in July 2014.

It's a timeless classic of children's literature and the third most-quoted book in English after the Bible and Shakespeare. But what lies behind the extraordinary appeal of Alice's Adventures in Wonderland to generations of adults and children alike? To mark the 150th anniversary of its publication, this documentary explores the life and imagination of the man who wrote it, the Reverend Charles Dodgson, better known as Lewis Carroll." Broadcaster and journalist Martha Kearney delves into the biographies of both Carroll himself and of the young girl, Alice Liddell, who inspired his most famous creation. Kearney's lifelong passion for Carroll's work began as a young girl, when she starred as Carroll's heroine Alice in her local village play. She discusses the book with a range of experts, biographers and distinguished cultural figures - from the actor Richard E Grant to children's author Philip Pullman - and explores with them the mystery of how a retiring, buttoned-up and meticulous mathematics don, who spent almost his entire life within the cloistered confines of Christ Church Oxford, was able to capture the world of childhood in such a captivating way
