Controlled descent actually contradicts suicide or terrorism, unless the pilot in charge actually was aiming for a specific target. None was apparent. Lots of rocks and nothing else at the impact point.
Terrorism would usually involve the terrorist making a statement claiming a cause. The whole goal of a terrorist attack is to gain attention and an audience.
A suicidal person most likely would take the shortest route from 38K to the ground, not an 8 minute descent.
Drugs may be involved. The pilot in the cockpit scammed the other pilot out to take drugs unwitnessed. Could have been an OD or the pilot was just out of it. That scenario doesn't account for a controlled descent though.
There is also rampant speculation in the thread about the pilot in charge being disabled due to health issues. That happens but would be an exrtrordinary coincidence.
Just too little information right now
No. All you need to know is this: One pilot locked out. Impossible for him to remain locked out even if the other was incapacitated. Suicide. By muzzie or otherwise. End of story.
That is what I am wondering too, why the 8 minute descent? Why not just dive straight into the ground?
I am still leaning toward terrorism but the 8 minute descent does seem very odd if it was.
