"Update: Alaska Airlines Flight Fuselage Blowout Investigation Continues"

NTSB officials provided an update on the mid-air blowout of an Alaska Airlines flight bound for Southern California, which suffered a violent decompression, creating a hole in the fuselage. The investigation is in the fact-finding phase, with no leading theory on the cause. Officials are seeking public assistance in locating a "door plug" that blew off during the incident. The flight attendants and crew were commended for their response, and further interviews with passengers and crew are planned. Both United Airlines and Alaska have grounded their 737 Max 9 jetliners pending inspection guidance.
