Was it just a coincidence to have 7 major disasters in 3 years, or did they all have the same root causes?
Thatcherism was in its pomp by the late 80s. Any sort of rules and regulations were “red tape” to be “ruthlessly cut” and so organisations did ruthlessly cut corners. That’s why Piper Alpha and the Herald of Free Enterprise disasters happened. The Marchioness sinking too.
You simultaneously had public expenditure as a dirty word. By the late 80s BR and London Underground were run down bordering on decrepit due to a chronic and deliberate underfunding. That’s why King’s Cross and Clapham happened.
I should not have included Lockerbie as that was a terrorist incedent and not an accident like the other disasters.
Lockerbie happened because airlines and airports refused to learn the lessons from the bombing of Air India flight 182 in 1985. That flight (and Air India flight 301, which blew up on the ground at Narita airport rather than in the sky because of a timing miscalculation by the terrorists) was brought down by the same modus operandi as Lockerbie: unaccompanied baggage containing a bomb.
Air India 182, killing more people than Lockerbie, also remains something of a forgotten incident.
