I didn't realize that pilots had been implicated.

Best bet is to follow the NTSB investigation, it's a slow process as you know, but one based on fact of finding.

For you to show up on the APC forum following a major accident, with the user name that you chose, and ask users to speculate on potential causal factors is not going to earn you any love.

I don't see this thread providing anything but speculation and flamebait - thread closed.
