Yep - the ATSB used to have a critical mass of competent personnel, competently led (although, in the case of the original Whyalla report, no one with sufficient competence in piston engine physics and chemistry).
ASTB no longer has that critical mass. Just like CASA.
Although it’s true and nice to say that there are some ‘really good people’ working in these organisations - some of whom I count as friends - the fact remains that the organisations are busted. The machines are busted. They are less than the sum of their parts and - what’s worse - governments no longer know how to fix them.
