Two back-to-back Senate committees will heavily scrutinize Boeing's safety culture and new whistleblower allegations today as a confidence crisis worsens at the American planemaker.  

The Senate Commerce Committee, which oversees the Federal Aviation Administration and Boeing, will kick off today's first hearing at 1000 ET. This will feature a panel of aviation experts who recently released a report criticizing Boeing's "inadequate" and "confusing" safety culture and has called for significant changes. 

The report states, "The procedures and training are complex and in a constant state of change, creating employee confusion, especially among different work sites and employee groups." The experts noted "a lack of awareness of safety-related metrics" across all levels of the company.
