Engineer Jem Stansfield investigates how the crash test dummy has become an icon for safety. For 65 years he has been crashed, smashed and impaled, evolving from a simple military mannequin into a highly sophisticated measuring tool.
Britain has more billionaires per head than any other country on earth, yet we're also the most unequal nation in Europe. We were told the super-rich would make us richer too, so why hasn't that happened, and what does the arrival of their astronomical wealth really mean for the rest of us?
Robert Peston explores China's dramatic economic slowdown and its potential impact on Britain. Visiting a ghost city and deserted factories in the north east, Peston reveals how China has built up one of the biggest debt bubbles in world history, and questions whether China's economic woes are worse than Beijing is admitting. In the booming south, Peston hits the shops to explore whether China can spend its way out of the slowdown - in the face of debts still growing by hundreds of billions of pounds a year.
On 22 May 1915, a collision at the Quintinshill signal box, near Gretna, became Britain's deadliest ever rail crash. Involving a military train filled with troops - most of whom were from Leith - heading for Gallipoli and two passenger trains, the crash claimed an estimated 226 lives and left hundreds more injured. The duty signalmen, George Meakin and James Tinsley, were found responsible for the disaster and were both jailed on the charges of culpable homicide. Neil Oliver explores the series of mistakes that may have caused the collision, the part played by the train companies and the government, and determines whether the investigation would have come to the same conclusions if it were carried out today. Dramatised reconstructions add to this compelling account of a tragedy which had a profound effect on several communities in Scotland, and remains the deadliest in the annals of Britain's railways.
