Someone inside Boeing knew exactly what they were doing, and are fully culpable for these accidents. Where was the FAA in all this?
I don't think so. AOA disagree was an option and from what I read Southwest ordered it. Why it was an option is a damn good question since it is apparently just software -- given that the proposed fix does exactly that and takes an hour to install...
