Haven’t seen it mentioned yet but maybe the “malfunction” was the pilot his/her/its/ self? These geniuses are all clotshotted and a mental hickup wouldn’t be out of the question. Seeing bad weather? Not doing the preflights? Not knowing the heading? Sounds like a whole string of mental foobars? There have been plenty of commercial pilot fade outs reported that have obviously been traced to the clotshots. Not the plane’s fault in any case-—it kept flying.
