I must remind that the last time such things occured on the Rally de Portugal we were on 2001 and the rally was still on the north. That was the year when Portugal lost all credit with the FIA. Of course now the rally is very well organised, but my point is: a week before the rally on 2001, a bridge on the Douro river fell, taking the lives of 40 or 50 people. I was 4 years old at that time and that’s one of my first memories. That day is just coming to my mind all the time today.
I know that this has nothing to do, but here’s a link to the explanation of that day: http://en.wikipedia.org/wiki/Hintze_Ribeiro_disaster
