Boeing’s own testing assumed pilots respond to runaway trim situation within 4 seconds [0]. Beyond that, the MCAS will have put the plane in an aerodynamic position where the pilot forces required to manually stabilise are too great. 4 seconds is not a lot of time. The Ethiopian pilots were aware of the need to disengage the powered trim and use manual control. They just couldn’t force the controls enough given the position the plane was in. The 737MAX is a death trap. It won’t fly again without significant redesign.
