I have finally finished and formatted my thing on the disaster!
This has evolved from what was intended to be a bit of rather short, intended-to-reassure-nervous-flyers puffery into being a rather long thing which I felt compelled to finish. I'm not sure who my target audience is for it. Maybe informed enthusiasts or beginning professionals?
Might even end up being the first chapter in an e-book along the lines of "Auntie Lily's Favourite Disasters"... it has certainly made me vow to never grumble about the regulations in health and social care again!
Here it is, kindly hosted by a chum:
