*** PURE SPECULATION No data to support ***: The contention would be that at some point the crew actually did use the stab trim cutout switches, leaving them with only manual wound (literally by hand, extremely slow), trim and elevator for pitch control, there was an IAS increase which reached an uncontrollable speed.
As I said, this possible chain of events is purely speculative based upon the previous sector having an AoA anomaly, the Boeing Bulletin,
APA MCAS revelation and a little bit of supposition. Thus far the data does not contradict this speculation, but I reserve the right to be wrong as new facts emerge.
Perhaps what is most apparent is that the imbecile Byron Bailey ought be facing a conga line of litigation. This like most accidents are a sequence of events. That idiot is no professional pilot. Just another MSM windbag.
Given Boeing's post factum missives, this accident sequence may well have been far more complicated than the pilots had anticipated given the previous flight history.
