The consensus agreed on earlier was that the NTSB briefings *are* an authoritative source (and rightly so!), they do not need to be separately quoted by 3rd party media/press refs, let alone by questionable blog postings or other "online media". And yeah, I'd expect people to actually have seen all NTSB briefings, otherwise they have really NO reason whatsoever to bother reviewing stuff here - if anybody can't be bothered to watch the NTSB briefings, then please just read the transcripts. Frankly, it is beyond me how you guys are tolerating this type of workflow and behavior, even perceiving me stating that as an "attack". How can it be an ATTACK to expect people to be familiar with the topic they're contributing to ? Honestly, all this goes to show the weaknesses and shortcomings of crowd-sourced encyclopedia-writing, there's no proper hierarchy, and if there's one, it's one where seniority and stylistic aptitude count more than a factual background. Yeah, this is kinda disappointing.
