Decided to fit an engine that didn’t really fit on an airplane for profits

• Decided to fit an engine that didn’t really fit on an airplane for profits
• Refused to re-categorize the aircraft
• Patched hardware with software and refused to document it
• Used an unreliable AOA vane and didn’t bother improving/fixing it
• Made all these savings by relying on a new system, MCAS
• So, surely the essential MCAS system was at least assigned to be designed and written by top senior engineers, right?

737 Max, how much money they try to save?
