In the midst of World War II, workers at a Welsh aircraft factory gave up their weekend off to build a Wellington bomber from scratch in just 24 hours. Why? To set a new world record.
With the country under attack and the war effort in full swing, worrying about world records might have seemed like a strange thing to do.
But after months of nightly bombing raids by the Luftwaffe, the Ministry of War was keen to show the world - friend and foe - that Britain could dish it out as well as take it.
And so, in collaboration with the RAF, the ministry issued a challenge to one of the factories churning out planes for Bomber Command - to build an operational Wellington bomber in record-breaking time, faster than the existing record of 48 hours set in California.
