Two America West Pilots on Trial for DUI

From CNN.com:

Two former America West pilots charged with operating a plane full of passengers while intoxicated may have consumed alcohol and smelled of alcohol but they could still walk and see, their lawyers told a jury Monday.

I don't understand why they'd do something this stupid. As Airline pilots, they are pretty much at the top of thier career ladder. So they go and ruin a career because they went out and drank it up the night before. Good job guys. I only hope the replacements are more responsible.
