How one tiny error brought 60 tons of glass, concrete and steel crashing down on a packed hotel lobby.
With its splendid modern architecture, the Hyatt Regency was the place to be seen in Kansas City in 1981. Beneath space-age walkways, guests drank, laughed and danced… not realising that the 60 tons of of glass, concrete and steel hanging above their heads was about to come crashing down.
One hundred and fourteen people died. But why? Was it cheap materials? Shoddy construction? Or a tiny error that seemed so insignificant that no one paid it any attention?
Cautionary Tales is written by me, Tim Harford, with Andrew Wright. It is produced by Ryan Dilley, with support from Courtney Guarino and Emily Vaughn.
The sound design and original music is the work of Pascal Wyse. Julia Barton edited the scripts.
