Portland International Airport was the scene of an alarming incident yesterday when an Alaska Airlines flight experienced a rapid decompression event in mid-air. The National Transportation Safety Board (NTSB) has been working diligently to gather information and shed some light on what transpired during the flight.
According to the data retrieved from the flight data recorder, the incident occurred at 1706.47 Pacific Standard Time, shortly after the aircraft took off from Runway 28L. At an altitude of approximately 14,830 feet and a speed of 271 knots, the recorded cabin pressure suddenly dropped from 14.09 to 11.64 pounds per square inch. This drastic change triggered a warning related to cabin altitude exceeding 10,000 feet and activated the master caution.
