Veteran NTSB investigator Greg Feith on this crash, he is one who isn't sure about the ''murder-suicide'' theory, and he knows what he is talking about, as he was the lead investigator back in the Silk Air murder-suicide crash
i agree with Greg, i mean the CVR clearly had audio of the captain trying to save the aircraft, issuing the mayday call in its final moments, someone who is committing suicide doesn't do that
i believe in my theory of the captain suffered from microsleep and that he touched the wrong controls (fuel switches instead of the thrust levers) with microsleep you have no memory of this afterwards, that might explain him saying ''i didn't do it'' but first officer Kunder asking this multiple times is also a red flag, why ask your superior this repeatedly and why not just put the switches back to run earlier?
