I have a lot of respect for the majority of cc who do a tough job very well. I would imagine however that the ITV claims about occasional lack of hygiene from a minority of our colleagues are probably true. I also suspect that other un-professional behaviour occurs from time to time, although I'd be surprised at any Cptn letting a non-pilot anywhere near the controls since the Aeroflot incident. My question to ppruners is what can be done to prevent these rare occurrences?
