If a ship runs into a large bridge, destroying both the bridge and ship, as happened recently in Tasmania, it is very difficult to see what either the naval architect or the bridge designer could have been expected to do about it from the structural point of view. The problem is not one for the structural engineer but for the local Pilotage Association. Again, aircraft cannot be designed to be flown into mountains.
