It happened as a two-day National Transportation Safety Board (NTSB) hearing into the 5 January incident on an Alaska Airlines aircraft began.
During the accident, Boeing informed investigators that it will implement design adjustments to prevent similar mishaps from occurring in the future.
The rupture marked the second big problem for the US aviation behemoth in recent years.
The plane’s crew detailed the dramatic decompression caused by the panel detaching mid-flight in almost 3,000 pages of documentation released before of the hearing.
The plane’s co-pilot informed the investigation that there was a “loud bang, ears popping, my head got pushed up into the [head-up display], and my headset got pushed, not off my head, but almost off my head.”
“It was chaos,” they explained.
“And then, just all of a sudden, there was just a really loud bang and lots of whooshing air, like the door burst open,” a flight attendant told me.
“Masks came down, I saw the galley curtain get sucked towards the cabin.”
