Boeing will be back in the hot seat Tuesday as the National Transportation Safety Board holds a hearing to present its findings from an investigation into the terrifying incident in which a door plug blew out of an Alaska Airlines 737 Max.

The mid-exit door plug separated from the Boeing 737 Max 9 passenger plane on Jan. 5, 2024, minutes after Flight 1282 took off from Portland International Airport.

The midair blowout in January 2024, which left a gaping hole in the side of the plane operated by Alaska Airlines, didn’t result in any fatalities, but it plunged Boeing into crisis as regulators and policymakers scrutinized quality lapses at the planemaker’s factories.
