Always was a dumb smeg move shipping oil or gas by large block trains rather than pipeline, the tragic accident in Quebec, Canada shows why.
So one accident, heavily publicized, is a reason NOT to use a method of transport then.
So, by your logic, what would you suggest?
I have heard so many reports of pipe fires/explosions both in the developed and developing world that pipes MUST be ruled out by virtue of your theory.
Road transport isn't even to be considered, since "one accident" means it is unviable, and road vehicles have accidents so often it's rarely actually reported in the media.
Ships are not always viable, due to a lack of suitable water, and I can think of a few man-made catastophes caused by ships running around due to human error.
So, enlighten us?
