In the first week of 2024, a Boeing 737 Max 9 passenger jet lost a rear door plug in midflight, terrifying people on board. The large door plug plummeted into the backyard of a high school science teacher in Portland, Ore. The Federal Aviation Administration ordered the grounding of similarly configured Boeing 737 Max 9 aircraft for weeks.

"This incident should have never happened and it cannot happen again," the FAA said at the time.
