Catastrophic failure at aluminum extrusion line - GIFs

[Ed Weldon]

Yes. There are very likely other factors in the failure. But the courts or even public opinion in the form of peer feelings seldom absolve the engineer's mistake even if corporate protection absolves them of legal liability. And then there are the effects of their own conscience. I can tell you as a former, now retired, licensed professional engineer that we mostly accept the responsibility for our own mistakes even if we aren't licensed. The engineer has the same moral obligation as doctors to design things, systems or whatever material object or outcome he creates or controls.
