....as mentioned above, it's someone on the 3rd floor trying to make a difference.
Just like pre-Command and SO technical interviews. Just like all the homework before the RT's. The route briefing exam, on and on....
Everytime there is a shuffle on the 3rd floor; someone has to appear to be making a difference. Whether it's better, more efficient or safer has yet to be determined.
As for the actual subject of "seat belts", we are not in the lawyer-friendly USA so put 'em on when it's needed, not cause your scared to get sued.
