I believe the drafting of Regulations / Requirements is a much more open, democratic and transparent process. SCs, being product specific are far more susceptible to commercial pressures.
Could be true, but what was Airbus and other manufactureers response to the SC process? If mute then all your points are vindicated.
My interest in other manufacturers doesn't mean to exclude other parts of the industry, it is only because taken as a group they should represent suitable knowledge and a floor to the ignorance base. So if we want to blame the FAA or Boeing, why was this not obvious at the time? or is it simply after the fact "I wish I had told you so?"
It seems we have left the barn door ajar but nobody saw it at the time.
