You could find/replace Boeing with NASA/Federal government with this entire article. Boeing has a crazy amount of oversight. This is the governments failure.
Boeing failed to meet the basic standards, but has been given a pass by NASA up til now. Bad welds? Sternly worded letter. Inadequate heat shielding? Well, it didn't get too hot so let's try with people. Bad valves? Just replace the broken ones, In sure there's no borderline valves from a systemic problem. Leaky tanks? Not a problem. Flaky thrusters that might not be able to make it to re-entry? Hold on there!
