Boeing faced further scrutiny during two Senate committee hearings on Capitol Hill, where witnesses raised concerns about the company's airplane manufacturing processes and the safety of its planes. One key witness, a Boeing engineer, acted as a whistleblower, alleging that the company ignored his safety concerns regarding the 787 and 777 aircraft. He criticized Boeing's use of excessive force to correct misalignments in the planes, resulting in gaps larger than the company's own standards allow.
Boeing defended its practices, stating that the 5/1000th of an inch gap is a hyper-conservative standard and that inspections have shown no signs of issues in the jets, even after years of service. However, the whistleblower maintained that such assurances are inadequate, emphasizing the critical nature of safety at high altitudes.
