BEANCOUNTERS...
someone mentioned clearing the BEANCOUNTERS from responsibility, blaming instead a lack of required standards
SO
Back in the beginning, there were no standards and we learned the hard way what had to be done to keep things safe and assure passengers there was as good a chance to get from A to B on an airliner as on a train, ship, car, or horse.
And they did it.
And then the regulators codified many of those same things.
BUT THEN came the cheapos. IF THE FAA or over seas version hasn't mandated it, then WE DON'T HAVE TO DO IT and can save money.
THE OLD GUYS shook their heads...they knew better. We are learning the same things over and over again that we knew 40 years ago.
all at the cost of passengers and crew.
So it is beancounters, because they have an excuse, an ENABLER in local regs that aren't as tight as a drum.
