Boeing realizing that there was a flaw in its flight simulators for the 737 MAX, pushed for and received a lighter and faster safety certification approval from the FAA; because the 737 MAX was called a derivative model of the main 737 line, both sides of the leadership aisle at the FAA and Boeing got the quick and speedy safety approval; putting countless lives at risk.

What legal challenges did Boeing face or is facing because of their decisions and how those legal challenges have impacted the company?
