pukinDog- Your assumption is that we are all perfect. To me it is irrelevant whether it was notamed or on the chart. When planning the lighting or signage it has to be considered that crews will miss exits if not properly indicated, especially at night in a poorly lighted area.
I can not understand the reason why the airport authority would not make it very clear that taxiway Mike was unusable by aircraft of a certain wing span especially after they have had previous incidents. They clearly did not respond to those previous incidents which to me is criminal negligence.
