I have nothing to do with NS but my AOC auditor who used to be a quality auditor for Jag/landrover came up with an interesting view on how we as an industry wave 2 fingers at safety. As he said if a car crashes or catches fire and it is seen as as a fault in design / manufacturer there is an immediate recall of those vehicles e.g. recently Toyota recalled millions of vehicles and modified for free. Do we see this sort of reaction in our industry, do we f..k. The attitude seems to be it will be all right just keep flying it and by the way it is the owners / operators problem ! As an operator I can vouch for how OEM's and regulators don't really take safety really seriously despite their protestations.
