The 1997 McDonnell Douglas acquisition led to their arrogant management culture replacing Boeing's, represented symbolically by the reference to The Economist cover September 10th-16th 1994 of camels fucking.

There have been many other safety defects and scandals swept under the rug, but they rarely make the news because they're detailed and complicated and corporate "news" isn't interested. Also, US presidents have defended them and US regulators run PR interference for them too.

The biggest one is the fact that unknowable 737 NG -6xx/-7xx/-8xx/-9xx structural fuselage elements including bear straps manufactured grossly out of spec by subcontractor Ducommun, declared "airworthy", and pounded into place on the Boeing fuselage assembly line on orders of management present greater risks of fuselage breakup during severe turbulence, runway overruns, and hard landings. There have already been fuselage breakups of NG airframes that 737 Classic aircraft survived more intact in similar circumstances. Most worryingly, there has been extensive retaliation against whistleblowers.
