Well said Darren, healthy conversation is the only way forward. As whatsarunway points out, this is not a place for mud-slinging.
I think this trend should be closed and let the AAIU / NTSB do there jobs and publish a preliminary report, then it should be discussed further. We are gaining nothing here and risk the media miss quoting replies and harming the image of this very delicate industry further.
