Both pilot & copilot fall asleep on redeye flight

Drowsy driving and its airborne counterpart "flying fatigue" are killers. The two pilots were way over speed and over altitude. The two airline pilots fell asleep on a flight from Baltimore to Denver. They quickly awoke to frantic calls from air traffic control.

Especially during the night it is easy to fall asleep in flight. The visual clues are gone and the gentle vibration can lull you into drowsy state where you are not 100% aware of your suroundings.
