A class-action lawsuit was filed Thursday against aircraft manufacturer Boeing on behalf of multiple passengers who were aboard an Alaska Airlines flight last week that was forced to make an emergency landing in Portland, Oregon, after a portion of the fuselage blew out in midair.

The lawsuit — filed on behalf of six passengers and a relative in King County Superior Court in Washington state, where Boeing is headquartered — alleges that “the event physically injured some passengers and emotionally traumatized most if not all aboard.”

On the night of Jan. 5, Alaska Airlines Flight 1282 was carrying 174 passengers and six crew members bound for Ontario, California, when a door plug of blew out just minutes after the Boeing 737 Max 9 had taken off from Portland.
