As France fell to the German armies in May 1940, 300,000 Allied troops were trapped on the beaches of Dunkirk. Their annihilation seemed certain - a disaster that could have led to Britain's surrender. But then, in a last-minute rescue dramatized in Christopher Nolan's recent film, Royal Navy ships and a flotilla of tiny civilian boats evacuated hundreds of thousands of soldiers to safety across the Channel - the legendary "miracle of Dunkirk." Now, NOVA follows a team of archaeologists, historians, and divers as they recover the remains of ships, planes, and personal effects lost during the epic operation. With access to previously classified files recently released by the UK government, they also uncover the truth behind the myths of Dunkirk - notably, a claim that the Royal Air Force failed to protect the stranded men from the Luftwaffe's constant bombing of the beaches. Featuring an exclusive excavation of a newly-found Spitfire wreck, NOVA debunks the myth and highlights the essential role that the RAF's iconic fighter played in reversing the desperate stakes that played out in the air above the beleaguered men.
The pyramids of Egypt are the most enduring monuments of the ancient world. From underground burial chambers they developed into soaring structures that revolutionized architecture. This film reveals the name of the man who designed the very first pyramid and shows how his ideas were refined and perfected, until pyramids eventually fell out of fashion altogether. The Egyptian pyramids have fascinated us for thousands of years. Who built them, how were they built and why? Experts across Egypt are discovering new information that sheds light on the Ancient Egyptians' pyramids and how they evolved. One theory poses that King Sneferu's Bent Pyramid was not a mistake. Recent discoveries show how the pyramids evolved from a mound of rocks and sand to flat, rectangular mastabas, to the pyramid shape, so famously exhibited in the Great pyramid of Khufu and beyond. Now the archaeology is being taken a stage further with new technology. The film shows how the next generation of archaeologists are finally piecing together the secret pyramid code which might have been used by the Egyptians.

Continuing his fascinating journey to rediscover the central role played by the Ottoman empire in Europe and the Middle East, Rageh Omaar explores the huge contrasts in the times of two very different Ottoman sultans. The most famous Suleiman the Magnificent in the golden age of the 16th century and the troubled reign of Abdul Hamid II in the 19th century when the Ottomans were dubbed 'the Sick Man of Europe'. Rageh examines the cultural legacy as well as the physical, religious and political architecture of Ottoman rule to find out what a Muslim world run from Europe was really like. It reveals the backdrop to the relationship between Islam and Europe today, how the Ottomans became central in the power politics of Europe and what could have happened had they succeeded in their successive bids to seize Vienna, then a key European capital.
