Cold Feet’s James Nesbitt presents this series examining the most devastating disasters to befall Britain in the past 60 years, asking why warning signs were often ignored and looking at the changes that were made in their wake.

From the Munich air crash of 1958, which devastated the Manchester United football team, right up to recent events, such as last year’s Grenfell Tower fire, which killed 72, survivors recount their ordeals.

Starting with the Ladbroke Grove rail crash of 1999, where the track operator was eventually fined for repeatedly ignoring a dodgy signal, this is frustrating, uncomfortable viewing.
