GR, your video is rather prescient, took nine years to get there though. As mentioned above, it seems normalisation of deviance reigned. Having worked for a US multi national it doesn't surprise me, as a salaried employee we were subject to a yearly appraisal which dictated your salary increase. After raising questions re non compliance of regulatory instructions was told by management to "Do what your told", earned 0% increase that year. I assume Boeing salaried employees would be in the same boat. Makes you wonder how sub standard parts make it into an airframe given the number of inspector stamps, think the most egregious example is the F-15 fuselage longerons which had too much metal machined off resulting in the nose complete with cockpit breaking away while conducting ACM. P-3 suffered too with leading edge ribs having too much metal removed.
