- The cockpit voice recording from Friday's Alaska Airlines incident has been lost.
- It got overwritten after two hours and investigators couldn't retrieve it in time.
- The NTSB wants that period increased to 25 hours, in line with European requirements.
Data from the cockpit voice recorder of the Alaska Airlines flight that lost part of its fuselage Friday has been lost, the National Transportation Safety Board said.
Jennifer Homendy, the NTSB chair, said at a media conference Sunday the data was overwritten because it wasn't retrieved within the two-hour window.
