Marine Maj.Daniel Daugherty, one of the prosecutors for the court-martial of Marine Capt. Richard Ashby, walks to court with charts for the prosecution at Camp Lejeune February 23. Ashby, on trial for the Italian cablecar disaster that killed 20 people, did not experience an optical illusion that would have made him think he was flying higher than he was, an accident reconstructionist testified Monday.
