Just saying.
In the UK, some coach companies have fitted a device to their vehicles which requires a "clean" breath sample to be given before the engine can be started. I was on a coach through a hot and heavily congested central London once. The engine overheated and cut out. The driver had to blow into a tube before restarting the engine. Not sure how that system would work with a flameout at FL120 though
