But of all the speeches he's given, six in particular may define his legacy as, in historian Doris Kearns Goodwin's words, "one of the best writers and orators in the presidency." Interviews with eminent historians and key figures in his writing process give rare insights into these iconic speeches, as well as the Obama presidency and the man himself.

For 65 years he has been crashed, smashed and impaled, evolving from a simple military mannequin into a highly sophisticated measuring tool. Jem meets a whole range of dummies from the past, present and future at crash laboratories in Sweden, the UK and US to discover how their evolution has mirrored car safety improvements. An affectionate look at a unique feat of engineering which makes you laugh, gasp and wince all at once.

For early aviators, conquering the forces of gravity was a daunting challenge. But black aviators had an additional challenge - conquering the forces of racism. Meet the men and women who took to the skies throughout the 20th century, proving to a segregated nation that skin color doesn't determine skill level. From biplanes to commercial jets, and from barnstormers to war fighters, meet the path-breaking pilots who opened the skies for all -- and contributed in countless ways to the development of aviation.

Is it possible that Ice Age people succeeded in crossing the frozen Atlantic Ocean to North America, thousands of years before the Vikings and Columbus? Two archaeologists believe so after discovering artifacts in Chesapeake Bay that bear an inexplicable resemblance to those from prehistoric Europe. Follow them as they combine old-fashioned excavations with exciting new DNA testing to prove their theory, answer their critics, and rewrite the history books.

Incredible Insects A captivating world of creepy crawlies exists all around us. And they are the biggest group of animals in the world, outnumbering humans 200 million to one. Thanks to millions of years of evolution, these invertebrates not only survive in almost every landscape known to man, but also thrive by means of fascinating, and sometimes bizarre adaptations. There's the Bombardier beetle that squirts a boiling hot liquid from its anus, the Assassin bug that turns its victims into soup, and the Parasitic wasp that lays her eggs inside her victims, until her young are ready to eat their way out. We end off with the biggest bugs on the planet: the Atlas moth with a wingspan of over 20 centimetres, the Hercules beetle that can carry 850 times its own weight, and the Giant centipede - big enough to catch flying bats from midair!
