    The Victor is one of the iconic aircraft of the Cold War, capable of carrying a nuclear weapon many times more powerful than the bombs that destroyed Hiroshima and Nagasaki.

    The Somme

    IWM curator Matt Lee has been working to discover the identity of a man featured in 1916 documentary film, The Battle of the Somme

    Filmed and first released in 1916, the film remains an important early example of propaganda as well as remaining a vital historical record of the early stages of the battle.

    Footage from the film is now synonymous with the First World War and is frequently used to illustrate documentaries covering the conflict. 


  • George Arthur Roberts

    George Arthur Roberts was an auxiliary firefighter during the Second World War.

    A uniform like the one he would have worn is on display in the new Second World War Galleries at IWM London and in this episode, curator Vikki Hawkins explores his story.


  • Taking to the skies

    IWM Duxford is still a working airfield and visitors can often see aircraft taking off and landing on a normal day.  

    The airfield marshalling team help ensure things run smoothly and this in this episode, we see instructor Johnny showing volunteer Sarah the ropes.

    Episode 4

    17 December

    A piece of the USS Arizona, one of the ships sunk during the attack on Pearl Harbor, arrives at IWM and curator Vikki shares how the team working on the new Second World War Galleries will use it to share the story of what happened that day.

    At Churchill War Rooms, we explore a hidden room where a top secret telephone line allowed Winston Churchill and US President Franklin Delano Roosevelt to have private conversations during the Second World War.

    The fire crew at IWM Duxford scramble for a drill as they rehearse how they will deal with every eventuality as the airfield prepares to welcome hundreds of rare and delicate historic planes this year.

    IWM’s Head of the First World War Alan Wakefield meets a man who has discovered a chest full of lost First World War letters and artifacts under a bed when he was clearing out his step father’s house.



  • Episode 5

    Coming soon

    Curator James Bulgin meets the granddaughter of a man who was murdered at Auschwitz to understand more about his life and to discuss the museum’s ambitious plan to honour his memory as part of our new Holocaust Galleries.  

    Meanwhile conservation staff are busy as a section of Nazi concentration camp barrack has just arrived from Germany for the gallery – but it’s soon clear that the priceless object will need a lot of specialist conservation work before it can be put on display.

    Plans to overhaul a First World War display at IWM North are underway, as curator Laura Clouting trawls through the museum’s vast store of objects and stories to find a fresh way to explain what life was like for soldiers in the trenches during the Battle of the Somme.

    And we find out how the runway at IWM Duxford is cleared of birds so that vintage aircraft can take off safely.   

  • Episode 6

    Coming soon

    The final touches are being made ahead of the opening of the new £30 million Second World War and The Holocaust Galleries at IWM London. Uniforms for the central cases are ready for display and museum staff have gathered for an unusual meeting to try out different poses to decide exactly what sort of mannequins need to be specially built for the delicate items.

    While the museum has countless personal stories, many communities and individuals are underrepresented across its collections. Improving the diversity of IWMs collection of stories and objects to show a wide range of experiences of war and conflict is critical and a growing focus for the museum.

    In the stores at IWM Duxford, curator Alan Wakefield is working to address this gap and has just acquired the bracelet of Sergeant William Robinson Clarke, the first black pilot to join the Royal Flying Corps, to help tell the story of his vital contribution to the war.
