I would agree that because of the way the investigation has unfolded, the incident was caused by factors narrowly applicable to BA38. Having released information that isn't considered to threaten continued and consistent operation of the Fleet or the Airport, I would assume AAIB is satisfied; if not, their inquiry obviously doesn't have disquieting implications.
Interesting assumption. Do you see any parallels with the response following similar one-off situations of TWA800 and Concorde? Or were these uniquely different combinations and of no relationship to such assumptions?
