The National Transportation Safety Board (NTSB) will hear testimony Wednesday in the second day of hearings into potentially inadequate manufacturing standards at aerospace company Boeing.

Scrutiny of the company became acute following the blowout of a door on an Alaska Airlines Boeing 737 Max 9 in January.

On Tuesday, the NTSB released public documents, including statements from Boeing workers who spoke of pressure to work too fast and a perceived lack of accountability for safety concerns.

Wednesday’s hearing began at 9 a.m. EDT.
