A survivor of the crash that killed five people including former Sen. Ted Stevens told investigators he didn't hear any strange engine noises before the floatplane struck a mountain north of Dillingham.
He didn't feel the plane tilt backward or forward either.
"They were flying along, and then they just stopped flying" said Deborah Hersman, chairman of the National Transportation Safety Board, recalling investigators' first interviews Friday with two of the four survivors.
As workers attempted to remove wreckage from the hillside, Hersman provided new details about the plane's condition, what investigators found on the ground and the flying history of the pilot.
