NTSB Chair Jennifer Homendy wrote Wednesday in a letter to leaders of the Senate Commerce, Science, and Transportation Committee. "Boeing has informed us that they are unable to find the records documenting this work. A verbal request was made by our investigators for security camera footage to help obtain this information; however, they were informed the footage was overwritten. The absence of those records will complicate the NTSB's investigation moving forward."
A Boeing spokesperson told Ars today that under the company's standard practice, "video recordings are maintained on a rolling 30-day basis" before being overwritten. The NTSB's
preliminary report on the investigation said the airplane was delivered to Alaska Airlines on October 31, 2023, after a repair in a Boeing factory. On January 5, the plane was forced to return to Portland International Airport in Oregon when a passenger door plug blew off the aircraft during flight.
