....What you say never happens happens all the time.
Perhaps you misunderstood what I said. I was talking about criminal behavior.
In the aircraft industry, anyone who knowingly signs off on inferior or negligent work that doesn't meet the called for standards and specifications...is liable under the law and can go to jail.
In the case of airline disasters anyone who is discovered to have knowingly approved of such work or materials goes to jail.
If as you say, you really work in this industry and are aware such gross violations, and also know of people being fired for refusing to sign off on faulty work (as you said)and you do nothing, then you are responsible and just as guilty of endangering thousands of peoples lives as well.
But then perhaps I misunderstood the degree of personal knowledge you claim to have of such things?
I actually wrote to our Sr. corporate officers, copied FAA, cooperated with an investigation and made sure a lot of things got fixed. Supervisors told me if they did the same, they would have lost their jobs. At Alaska Airlines, and mechanic named John Liotine wore a wire and helped get supervisors busted by FAA. He also wrote-up the very jackscrew which failed, causing multiple deaths. The documentation was penciled-off by ASA managers, but in the end the FAA and management colluded in their findings, stating that failure occured because someone used the wrong lubricant which caused corrosion. Never mind the thing was at its design limits on the "C" check. No one went to jail in that criminal fiasco. Dateline NBC did a story on this!
