 The criminal charge against Boeing has come as a result of an incident earlier this year in which an unused door panel fell off a brand new 737 MAX shortly after takeoff. That, together with mounting evidence of poor quality controls at Boeing's factories, was enough to persuade the US Department of Justice to reopen its criminal case against the company. The aerospace giant will now have to pay an extra fine of $244 million, while an independent monitor will be appointed to ensure it cleans up its act.
