Sorry to be so blunt but
The Captains only have to say NO and the flights don't happen. They have a responsibility to the passengers. If this is guaranteed to lead to them being fired then they resign first, but it's too late after a crash to say "It's because of this this and this".
Sadly in this day and age of 'European Aviation Safety', you cant count on the authorities to lift a finger but its always worth a try, even if anonymously. Also, I know that for every Captain that does have the balls to stand up and say no, there will be some spineless little prick willing to take an unsafe flight anyway but that's just the way it is in this business.
I hope if its as bad as being made out then all the good guys at RE find new employment soon, but in the meantime I'm afraid its time to make a choice. And for those posters about to tell me that morals don't feed hungry mouths, I say to them that An accident is often career stunting and a death-in-service payment wont keep a roof over loved ones heads.
Standing by for incoming.
