Either way, it is yet another well credentialed overseas commentator finding fault with an ATSB report.
Not really. It is just a blog from a guy who has a bee in his bonnet and finds fault in any report by any authority that does not focus above all else on the single issue of maintaining a zero slip angle of bank. ATSB, NTSB, AAIB, DTSB and any manufacturer who didn't change their manual after he wrote to them; he knows better than all of them of course.
