Boeing's 737 MAX had a flawed automated system (MCAS) that pilots were not informed about. Internal communications revealed engineers knew about the issues: one employee wrote 'this airplane is designed by clowns who in turn are supervised by monkeys.' After crashes in 2018 (Lion Air) and 2019 (Ethiopian Airlines) killing 346 people, investigations showed Boeing had pressured the FAA, hidden safety data, and prioritized speed-to-market over safety. Boeing was charged with conspiracy to defraud.
