DC-ATE - Re trained guys, yeah, thought so. Re "skeptic", yep, I'm a skeptic too...of a process that contemplates releasing such data to a wide group under the assumption that they will come up with as good or better a report than the specialists who've done the work in some cases, for decades.
I know of no cases where the reports had the scent of "compromise" due to political, legal or corporate influence.
I do know of several final reports in which dissenting opinions by interested parties and even designated investigators are included.
What I have seen far more of, is, once the confirmed truths regarding an accident are in print for all to see, it is special interest groups, and that includes airlines, pilots' associations and the regulator, that embrace, dismiss, deny or "correct" conclusions according to their own interests.
