Yes - I occasionally like to put the pin
It's the alarming frequency of your "occasional" that earns you the title...
With regard to everything else you say we only differ on the airworthiness issue. I believe the probability to be low that an actual airworthiness issue had a causative influence on the accident but I find it to be poetic justice that "the system", (whoever and whatever that might be in this instance), might have, in trying to gloss over some "paperwork peccadilloes", opened a veritable Pandora's Box. I will freely admit to a modicum of pleasure in their squirming since it was apparent to me after the Falklands "accident" that this aircraft was far more dangerous than people were telling.
