No instant answer has come to light as yet. A bunch of experienced ATSB guys are getting paid much more than us to study all the facts and find an answer to this tragedy. I understand your curiosity for what happened, the answer may save you or i from the same outcome. If you've read the ATSB web site post and the NT news clippings then you know as much as anyone.
