..... and just to think that Air France pilots used to ( and maybe still do ) get a little bottle of wine with their in-flight dinner.
Now for all we know the pilot in question might just have used a mouthwash, e.g. I've just got the one from my bathroom cabinet ( i.e. Tesco's Extra Strength CoolMint ) and a glance at the ingredients reveals: Aqua,
Alcohol (21% w/w), Glycerin, Polysorbate 20, Sodium Benzoate, Aroma, Cetylpyridium Chloride, Sodium Saccharin, Sodium Fluoride (0.05% w/w), Benzoic Acid, CI42090, CI47005.
veritably an almost eye watering array of stuff, including alcohol ! 
So one could well imagine that if I rinsed my mouth with it, and maybe even managed to mistakenly swallow some of it, then I too could likely register on a breath-test that's seemingly set so low.
Thus, and before we forget that great tradition of 'being innocent until PROVEN to be guilty', let's wait and see what comes of the blood test shall we ?
