Hapzim,
You could, of course, take the horses a*** approach, and announce that if they do what we fear, we shall immediately seek a law increasing the allowable blood alcohol level for flight crew that affords a similar degree of safety.
This would only be logical since a degraded level of safety is clearly perfectly acceptable to them.
And I forgot to mention that even in this little third-world island ,we have an antique law (probably UK heritage from the 1930s) that prohibits truck drivers from more than 10 hours driving duty in any one day. I have a suspicion that the haulage industry in the EU is probably more restricted than the aviation industry. Anyone know the facts?
