Upside-Down Sensors Caused Proton-M Rocket Crash 323
Michi writes "According to Anatoly Zak, the crash of the Russion Proton rocket on 1 July was apparently caused by several angular velocity sensors having been installed upside down. From the source: 'Each of those sensors had an arrow that was supposed to point toward the top of the vehicle, however multiple sensors on the failed rocket were pointing downward instead.' It seems amazing that something as fundamental as this was not caught during quality control. Even more amazing is that the design of the sensors permits them to be installed in the wrong orientation in the first place. Even the simplest of mechanical interlocks (such as a notch at one end that must be matched with a corresponding projection) could have prevented the accident."
A review of the quality control procedures used by the contractors responsible is underway.

Quality Control in Russia basically consists of hitting it with a mallet, and if it doesn't fall apart on impact, it passes.

That's the problem. Some parts were made by subcontractors in Australia, where up is down, rats are as tall as humans and hop around and flat-chested 30-years-old women are classified as underage teenagers.

Ive seen RAM modules installed backwards. "Wait!", you say, "Isnt there a notch which prevents that?" Well, yes, there WAS a notch...

If only they had labeled, with the arrow, the words "up", and put another arrow down, with the letters "dn" for "down", then none of this would have happened.
Except that "dn" upside-down is indistinguishable from "up". Murphy strikes again?
