Great informative post, Thank you Yoko.
The problem mentioned in your final paragraph is that an official inquiry held by experts is one thing - a rumour panel with everybody from experts and concerned daily operators to schoolboys and air fans is another.
You are caught in the frustrating position (as are others) of trying to present reasoned arguments to a mixed bag of folk.
The other problem is that a few pages on, only the concerned operators will recall most of the clarifications and repetition often becomes necessary to “educate” others and late comers.
Thanks for taking the time. Only after the final report will speculation stop.
