For its role, Boeing is facing mounting criticism for both its handling of these disasters and potential culpability in not doing enough to avoid tragedy. In May 2019, it was reported in the Wall Street Journal that Boeing knew of problems with its safety alert system a year before the crash in Indonesia. Beyond this, Boeing failed to inform pilots or airlines even of the existence of the MCAS. The company maintains that, while no disclosure about the MCAS was made, the system itself was always embedded into each aircraft, thus ensuring that test pilots flew with this feature in place. Yet, this has done little to quell pilot and crew frustration over this lack of open transparency. Family members of the victims in these crashes are also pursuing legal battles against Boeing, arguing that the company was negligent and provided unsatisfactory instructions on how to solve potential system malfunctions.
