simple, a commander is always in charge when all goes well but the moment there is a stuff up, it's management's fault for putting commercial considerations before safety, or it's fatigue caused by untenable rosters, or it's latent factors brought on by systemic failures, or it's the wife's fault for be such a nag, or it's the kid's fault for not listening, or it's natures fault for the weather............
