It not just about being productive, its the way establishing an argument works, in proposing a hypothesis you need to reference sources upon which you build your argument. At least that is the way I was taught. As I said not that I am saying that blog is wrong (anon blog it should be said, no reference to authors) but what we need to see is a graph of center of lift vs attitude vs speed vs throttle position. Surely that is not proprietary or design secrets, its flight / performance characteristics which every pilot flying the type should be familiar with. Also from what I understand there is multiple ways of disengaging MCAS, surely the pilots were aware, or should have been aware its tad touchy but who knows its all speculation at this stage, but I am sure the facts will come forth soon. But I am going back to the problem of over-automation and the belief that the computer will fly the plane. Remember that Asiana Airlines Flight 214? "The NTSB found that the "Mismanagement of Approach and Inadequate Monitoring of Airspeed led to the Crash of Asiana flight 214". The NTSB determined that the flight crew mismanaged the initial approach and that the airplane was well above the desired glidepath. In response, the captain selected an inappropriate autopilot mode, which, without the captain's awareness, resulted in the autothrottle no longer controlling airspeed. The aircraft then descended below the desired glidepath with the crew unaware of the decreasing airspeed."
