Co-pilot on wayward flight denies any arguing, sleeping

(CNN) - The co-pilot of a Northwest Airlines flight that overshot the runway in Minneapolis, Minnesota, by 150 miles says he and the pilot weren't asleep and they weren't arguing.

However, Richard I. Cole, who spoke to CNN affiliate KGW-TV from his home in Portland, Oregon, wouldn't say much more on Friday. He said an investigation will reveal what took place.

After repeatedly saying he couldn't talk about the case, Cole said that contrary to media reports, "Nobody was asleep in the cockpit. No arguments took place. But other than that, I cannot tell you anything that went on because we're having hearings this weekend, we're having hearings on Tuesday. All that information will come out then."
