BGG,
Thank you for replying. I’m definitely not trying to be obtuse but my eloquence may have failed me.
The point I was trying to make in my first three paras was this. Perhaps rather than try to illustrate or investigate fundamental, institutional or even personal failings one should do that using an isolated (tragic) accident as evidence within a wider context - the vehicle for which I am unsure of - as opposed to looking at the accident specifically in order to show the wider failings.
Yours,
Orca.
