I'm not sure if accident is the right term to describe the outcome of flying VFR in blatant IMC at low level in a built up area.
However that particular event is seen, I'm certain it was an accident; it was certainly not a deliberate occurrence.
But rather than get into that discussion (which has been previously done in great depth), the relevance was the plethora of these new NOTAMs and how they quickly become "white noise".
