The Captain (can't remember name, but it is the older pilot) has had TWO PRIOR instances of alcohol related "discussions with police in his hometown. Both of these instances/events were at his home. One involved an "assault" on his wife, the other involved his neighbors in the apartment below his in shich he felt they were making too much noise and he "confronted" those neighbors who called the Police in that instance.
So - there is an "alcohol" related background with this particular pilot (the older one).
