Fact check
Is it true: Boeing 737 MAX Cover-Up?
Yes — this is confirmed.
MCAS was added to the 737 MAX to compensate for aerodynamic changes from larger engines. Boeing did not fully disclose it to pilots or the FAA. After Lion Air 610 (October 29, 2018) and Ethiopian Airlines 302 (March 10, 2019) crashes both traced to MCAS-driven nose-down commands, Boeing's internal communications — released through House Transportation Committee investigations — showed employees joking about "designed by clowns supervised by monkeys" and actively working to hide MCAS from FAA. Boeing agreed to a $2.5B deferred-prosecution agreement with DOJ in January 2021 (fine + victim compensation + fund for airlines). After the January 2024 door-plug blowout on Alaska Airlines 1282 (737 MAX 9), DOJ found Boeing in violation of the DPA; a plea agreement with criminal conviction is pending (as of 2024-2025).
