Hat: Shouldn't be needed. This thread has the possibility of getting out of control. Please keep posts civil, logical, and try toi steer towards technical and technically useful (even though this is OT) There are things which can be learned here which are useful in the wider sense - aspects of fail-safe system, human error, never laying odds of more than X to Y when people are involved (as advise by Harry the Horse IIRC / Damon Runyan) and more. These will be lost if we get too far off track.
