Boeing 's safety and quality were under fire again in two Senate hearings on Wednesday as the manufacturer faces mounting scrutiny after a midair door blowout and near catastrophe on one of its planes in January. A Boeing engineer-turned-whistleblower testified before a Senate panel, reiterating his allegations that the planemaker cut corners to move wide-body planes through the production line, despite flaws. "I believe that Boeing can do better and that the public's trust in Boeing can be restored," he said in prepared remarks to the Senate Homeland Security committee ahead of the hearing "Examining Boeing's Broken Safety Culture: Firsthand Accounts." New plane deliveries from Boeing have slowed as the Federal Aviation Administration ramps up its scrutiny on the company's production lines. A separate hearing, before the Senate Commerce Committee on Wednesday, addressed Boeing's safety culture after a report issued earlier this year from an expert panel ordered by Congress found a "disconnect" between Boeing's senior management and other members of the organization on safety culture.
