The Exxon Valdez spill happened after midnight with a man at the helm who'd slept only four hours the night before; Chernobyl and Three Mile Island also occurred late at night and involved human error. And the assistant captain who crashed the Staten Island ferry into a pier, killing 11, admitted that he felt exhausted before the accident.

"Many people want something associated with morals or management or…alcohol," Dinges remarks. "Those are far more glamorous.

And that is the hallmark of sleep deprivation."
