from the Cube
is a regular feature run by EDN, in which readers
tell tales of interesting experiences in their engineering careers.
This particular story is very interesting and highlights why you should
never accept that a solution to a problem has been found until you fully
understand the initial cause. What's really scary is that evidently
this product and its 'cure' are probably still doing active service
in airplanes around the globe. It is hard to believe that a QA department
would sign off on such a deal.
