Yet another evidence of the relentless push to meet market deadlines at the expense of long term safety. Same thing happened with Toyata. The engineering designs were not ready but any professional with integrity and moral values who objected to the "push to market before safety ready" were sidelined and replaced. It is happening in the auto-industry, airline, health and almost all modern industries to capture market share & the ever-important bottom line and stock price.
Remember Airbus was seriously behind schedule. They were not ready to roll off the production line without adequate "safety tests". But like the Nasa Space shuttle disaster, anyone who tried to caution the reckless "speeding train" on a collision course" was blanked out. I know I was. God knows how many more were silenced in unfortunate accidents like drowning in a hot bathtub.
There is profitability in manufactured or "allowed to happen" disasters. Those who knew beforehand of the Australian Transport Safety Bureau (ATSB) interim report, would have shorted Rolls-Royce shares for a windfall.
