The Alaska Airlines flight that lost a section of its cabin wall midflight on Friday and had to make an emergency landing became the latest disaster to strike Boeing 737 MAX aircraft.

Due to the plane’s cabin panel blowout and landing, U.S. flight regulators grounded certain planes for safety checks. This is not the first time that groundings of 737 MAX planes have been ordered, and several fatal crashes at one point caused an international grounding of all MAX-family aircraft previously.
