The jet had performed a flight from Washington DC and whilst on approach the flight deck crew became aware of a crack in the inner windscreen. Alaska Airlines said the crew "followed their checklists and the aircraft continued safely to its destination as scheduled."
In a statement to U.S. media, Alaska Air confirmed the aircraft was "outfitted with five-layer windscreens that have an outer pane, three inner layers and an inner pane. If an inner pane cracks, the other pane and layers can maintain cabin pressure. The aircraft will be inspected and repaired by engineers on the ground."
The plane was carrying 159 passengers and six crew at the time of the incident and the windscreen layer has been repaired and the jet is now put back in service.
