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 first six minutes of the flight to Southern California’s Ontario International Airport were routine. The Boeing 737 Max 9 was about halfway to its cruising altitude and traveling at more than 400 mph (640 kph) when passengers described a loud “boom” and wind so strong it ripped the shirt off someone’s back.
