Thanks for the replies! It is a question no one can seem to answer very well, yet, no one is worried about it.
If a pilot does have such a case on his/her last company, I personally think the company should take into consideration of the event itself and if the pilot is not at fault then there shouldn't be a problem. Peter was found that he did nothing wrong and actually did something the book told him not to because his experience and knowledge prevailed which saved lives, yet the poor guy couldn't get work regardless of the thousands of hours he had total on type and PIC and working for one of the most famous airline in the world.
