"Big John"
How do you know this individual was not one whose body assimilated
alcohol in a manner that did not effect normal activities by any
measure (test)? Were the results of any impairment tests published?

One last shot over the bow. How many stone cold sober individuals have
flown through controlled airspace (the alleged activity)? Were their
ticket revoked?

There is a tendency irrationally condemn intoxicated people. But in this
case, the pilot was objectively intoxicated and he clearly acted in a
reckless and careless manner. Whether he was sober or drunk while doing
what he did, it would seem to justify pulling the ticket. The alcohol is a
reasonable explanation for the bizarre behaviour. Without the alcohol, the
guy needs medical help,
