 The Boeing jetliner that suffered an in-flight blowout over Oregon was not being used for flights to Hawaii after a warning light that could have indicated a pressurization problem lit up on three different flights. A federal official said Sunday, Alaska Airlines decided to restrict the aircraft from long flights over water so the plane could return very quickly to an airport if the warning light reappeared, said Jennifer Hommendi, chair of the National Transportation Safety Board, Hommendi. Cautioned that the pressurization light might be unrelated to Friday's incident in which a plug covering an unused exit door blew off the Boeing 737 MAX-9 as it cruised about 3 miles, 4.8 km, over Oregon, the warning light came on during three previous flights, on December 7, January 3 and January 4, the day before the door plug broke off. Hommendi said she didn't have all the details regarding the December 7 incident but specified the light came on during a flight on January 3 and on Jan. Or after the plane had landed.
