Forensic Files - Season 8_ Episode 42 - Flashover - Full Episode

"A small routine fire suddenly erupts into a deadly inferno and kills 31 people." At the King's Cross Underground Station in London, what seemed like a minor blaze on a wooden escalator quickly became a catastrophic event. To solve the mystery of its rapid spread, investigators used pioneering computer simulations. They discovered the "trench effect," a phenomenon where hot gases and flames behave in unexpected ways, turning a simple fire into a lethal trap in seconds. This episode reveals how forensic science and fluid dynamics converged to explain a tragedy that changed fire safety forever.
