Sometimes, a high-functioning alcoholic can hide their addiction for years in their workplace. They appear very professional, often in charge, but after many decades, that old and filthy liquid narcotic will take its toll. Eventually, it demands its payment in full, and their once fantastic flying machines crash and burn in a spectacular blaze, much like the Hindenburg disaster. They had been sailing majestically in a clear blue sky, but then there's a helium hiccup when one day, they light up a cigarette after filling up with ethanol, and suddenly, there's a terrible explosion.
