DozyWannabe - wanting not to intrude on the sense of perspective and rationality created by your excellent post, I want only to say that some discussion did occur about the lawsuit filed by the Southwest pilots union (perhaps it took place on one of the other threads); this is pertinent inasmuch as the complaint in that case lays out, in pretty strong detail and depth, the manner in which Boeing's 737 MAX program was determined by its need to keep the airline a happy customer. (SWAPA filed its case in Texas state court; it then was pulled into federal district court by Boeing under the federal judicial code, but sent back to state court because Boeing's basis for removing it into federal court was ruled (by the federal judge) to have been invalid.)
