Courtney,
I am a 737 Engineer (Albeit -3/4/500's some 7 or 8 years ago) and the manuals did have a one-liner in the depths of some 1,000 pages about returning switches to their normal positions. But I never knew it until after this incident.
Of the four people charged and later convicted and sentenced in-absentia for this accident; none of them could be "blamed" for the recorded cockpit confusion, misinterpretation and prolonged inaction of the crew during this tragic flight.
However, the real question on this thread is: If the MAA were in the same position who would get the Chop? And why?
Without real independence and a directive to find the actual root cause, the end result of any accident or incident investigation is not likely to be clear or beneficial to anyone.
