The world’s worst disasters all have one thing in common: none were triggered by a single cause. Each was the product of a string of bad decisions… a catalogue of errors that SMITHSONIAN CHANNEL reveals for the first time in TEN STEPS TO DISASTER (Tuesday 7th, 8pm).

This eye-opening documentary series uncovers the series of mistakes that led to the worst disasters in history. From substandard materials, bad designs and shoddy workmanship, to poor communication, chaotic organisation and lethal protocols, TEN STEPS TO DISASTER uncovers major new revelations about the world’s most infamous human catastrophes.
