To be fair, Beanbag, I think Rob is not far off the mark in many respects. How much has been done about aircon fumes? Or the lack of feedback from Airbus FBW controls? What about EASA's contempt for scientific or expert input into the new FTL regs? And what reactions do we get if we pro-actively report a concern over systems or circumstances we consider may lead to an accident, rather than just sticking to report post-event? The regulators and companies all stick their head in the sand, especially if it's going to cost money, and when things do go wrong just look for scapegoats before seeing if something needs fixing.
