"NTSB Criticizes Boeing's Lack of Cooperation in Alaska Airlines Blowout Probe"

US crash investigators accused Boeing of failing to cooperate in the probe of a 737 Max 9 panel flying off, with NTSB Chair Jennifer Homendy criticizing the lack of documents and information provided. Boeing responded by stating it had provided employee names and was fully supporting the investigation. The possibility that no documents exist at Boeing to explain how the airplane left its factory missing bolts was revealed, leading to a dramatic day of testimony at a Senate Commerce Committee hearing. The NTSB is focused on 25 Boeing workers assigned to 737 doors and is conducting additional interviews at the Renton, Washington, factory. Senator Maria Cantwell demanded Boeing provide additional information to the NTSB within 48 hours, while the US Justice Department is scrutinizing the incident for potential criminal prosecution.
