No, we have not all done it. Not by a long shot.
So much speculation about what may have occured...no information, but everybody is an angry expert. Speculation and guesswork is such a professional trait, is it not?
We are not provided with the identity of the reporting party, w(h)eather it be a gate agent, first officer, or the easter bunny. We are not provided with the details of any conversation, offers, threats, or other interaction that may have taken place between any of the involved parties. The only information provided is that a pilot was reported for a potential alcohol violation, and subsequently failed the test and was fired. That's all.
Management that upholds company policy is not bad management, nor bad actors. A contemporary that upholds company policy is not a bad collegue.
A pilot that shows up for a flight intoxicated beyond the legal limits, or intoxicated in any manner (above or below the legal limits) is an idiot and should not be in the cockpit.
A prior poster attempted to cross this topic with that of a 16 hour duty day. A pilot that finds himself or herself fatigued beyond safe limits at the end of four hours, eight hours, ten hours, or sixteen hours, has every obligation to remove him/herself from duty. I've certainly hit a point in a day when I notified the company that I was unable to proceed safely, legal duty notwithstanding. I have refused to go on; safety of flight is the final word.
Someone, we don't know who, declared a safety of flight issue and that indeed did bear out to be the final word based on a legally binding verification of the facts. Offers, deals, and politics notwithstanding, this pilot tied his own knot, wore his own noose, and pulled his own lever to ultimately hang himself. Where does the final responsibility and authority lie? As pilots, we know it rests with us. Trying to spread the blame beyond that is a pathetic effort at cowardice in evading our own responsibility. A man who picks up a bottle knowingly, picks up one end of the stick. When one picks up one end of the stick, one picks up the other. Pick up the stick, accept the responsibility thereof.
Such is the price of being an adult.
