I must admit these things couldn't happen in Canada, where they methodically test these things. In fact, things work best when they are mindlessly methodical. It's when things become a bit complicated, that 'nose to the grindstone' doesn't work. I remember that I became the most hated in the old company when I noticed a backup safety battery was totally rigged up in the wrong way for seismic. The plates would shatter in the tiniest earthquake! Naturally, they killed me, since this would require the closing of an entire plant. I suppose it got fixed eventually.
