to demonstrate how this is all Flt Lt Cunningham's fault.
WHICH I DO NOT BELIEVE FOR ONE SECOND.
I don't think anyone is insinuating anything of the kind - not least because he had nothing to do with the over-tightened bolt. As others have said, the inquest evidence to date has made it plain that there were a lot of people (yes, including Sean) involved in the chain of events leading to the accident. I haven't seen anyone attempting to pin blame, apart from a few half-hearted attempts to start a conspiracy theory!
