The captain of the tugboat that pushed barges into the Interstate 40 bridge in Oklahoma says he screamed in frustration as cars and trucks plunged into the Arkansas River. Fourteen people died in the May 26th, 2002, collapse of the bridge near Webbers Falls. A federal report says Captain William Joe Dedmon spoke with investigators three days after the crash. He denied fatigue was a factor in the crash, but he says he doesn`t know what happened. Dedmon told National Transportation Safety Board investigators the last thing he remembers before the collision is passing the last buoy as the barges approached the bridge. Attorneys for Dedmon and his employer, Magnolia Marine Transport, say Dedmon blacked out before the tugboat ran the empty barges into a bridge support. A final report that will include conclusions and recommendations is still pending.
