Same article:

> By July 9, it is transpired that investigators sifting through the wreckage of the doomed rocket had found critical angular velocity sensors, DUS, installed upside down. Each of those sensors had an arrow that was suppose to point toward the top of the vehicle, however multiple sensors on the failed rocket were pointing downward instead.




This is why the guy who inspects and signs off on the work must not be the same guy who does the work.

Yes, the article confirms what I am talking about.


Backwards installation of G-switches crashed the Genesis probe on its return to earth [1].

This part was news to me:

> On January 6, 2006, Ryschkewitsch revealed that a pre-test procedure on the craft was skipped by Lockheed Martin, and he noted that the test could have easily detected the problem.


From the photo of the switch, I'd say the package design could use improvement. The orientation of it is not obvious.


Just so.

Twenty minutes of a designer role-playing an assembly tech installing those components (with the mindset of trying to fail) might have gotten us a "this can only fit one way" result.
