The Lexington Herald-Leader reported that National Transportation Safety Board officials told families that in talking to the control tower when the pilots were about to take off, one of the pilots gave the wrong flight number and said "Toledo."
The commuter jet was bound for Atlanta when it crashed Aug. 27, 2006, as it tried to take off from the wrong runway at Lexington's Blue Grass Airport. The pilots also initially boarded the wrong plane.
Kyra Frederick's husband, Bart Frederick of Danville, was one of the passengers who died. She said there were a series of mistakes that were the beginning of a bad flight.
The crash killed 49 of the 50 people aboard.
Frederick and Charlie Scales attended NTSB briefings last week in Lexington, Ky., and said they learned of the apparent "Toledo" mistake then. Scales' brother-in-law, Gregory Threet of Lexington, also died aboard Flight 5191.
