That looks like a pretty basic flaw that should have been found and fixed
long ago, particularly as it's happened before, in Ireland!

Or similar failure modes on the Comet aircraft. Don't they teach this on
the first week of engineering courses, any more?

It’s what happens as the result of “efficiency�. In days gone by there
would be a core of long serving engineers in an organisation with the
corporate memory of what not to do again. These days it’s fashionable to
talk up changing jobs every few years and easing out the older experienced
staff because they are expensive. The modern practice is to claim that
everything can be captured in a specification or a standard. Unfortunately
that’s not the case....

Many outfits are doomed to keep on repeating the same mistakes because of
high staff turnover.

I agree that corporate memory is important, but proper engineers
are taught universal memory - which can then be applied to
whatever corporate they are working for this week.
