Keep in mind I don’t know exactly how those conversations went between Boeing and the FAA, nor do I know exactly who my dad was referring to when he said Boeing (the head of engineering? head of safety? A group of people inside Boeing? Was Boeing unified in its opinion or was this concentrated in the area of engineering my father worked in?) Grounding an entire class of plane is not a decision made lightly because of the huge financial and political implications. My takeaway is Boeing leaned towards grounding and the FAA did not and on balance the plane stayed in the air while Boeing worked on the fixes.* *EDIT: This is probably a conversation that happens after every crash/major-incident and hindsight is 20/20.
