Last week, a pressure leak occurred on the International Space Station. It was slow and posed no immediate threat to the crew, with the atmosphere leaving the station at a rate such that depressurization of the station would have taken 14 days.
Eventually, US and Russian crew members traced the leak to a 2mm breach in the orbital module of the Soyuz MS-09 vehicle that had flown to the space station in June. The module had carried Russian cosmonaut Sergey Prokopyev, European Space Agency astronaut Alexander Gerst, and NASA's Serena M. Auñón-Chancellor.
[...] The drama might have ended there, as it was initially presumed that the breach had been caused by a tiny bit of orbital debris. However, recent Russian news reports have shown that the problem was, in fact, a manufacturing defect. It remains unclear whether the hole was an accidental error or intentional. There is evidence that a technician saw the drilling mistake and covered the hole with glue, which prevented the problem from being detected during a vacuum test.

Um, no. You get quality control by doing the work correctly AND having someone unrelated to the manufacturer inspect that work and sign off on it.
You're welcome.

Quality Control is about carefully controlling the amount of quality that can get through.
On Ars someone mentioned that this is probably a cultural problem. Item A. Someone maid a mistake and was so afraid of reporting it that they tried to fix it and hope nobody noticed.
This "we'll find the full name of who did this" is a symptom of that cultural problem.
Or as software developers know it: FDD.

FDD explains the morass of ineptitude that is called Windows. Also Gnome3 and the new flat-look apps. In the old days we used to call this regression.

Regression below the mean?
