In article , Peter Dohm says...
I've both heard and read many times that an accident is nearly always the
result of a series of errors;

Exactly right ,I've heard it was usually a combination of 3 things that cause
accidents and if any one of them was missing it wouldn't have happened.

and it's a tribute to your design that it took
such a dramatic series to reach this unfortunate conclusion.
