So I read some comments which led to wiki which led to the 1955 Le Mans disaster which I had seen briefly, BUT never like this. (The track looked so festive and the cars really great designs) However the lack of safety was so knaive combined with poor technology and bad driving led to this.
Amazing that this footage exists - VERY GRAPHIC and may disturb, 1st 25 seconds is all you need to see to understand what happened and how quickly and viloently car accidents can happen!!!!!!!!!!!!!!
If you want to see it - Go to youtube and put this in to their search function
