> [Boeing's] own engineers ... “concluded that the system complied with all applicable FAA regulations.” Four years after the engineers wrote that opinion, the system failed twice, killing more than 300 people. It is a really big leap to conclude that this system would not have failed 4 YEARS after inspection if the FAA had done the inspection itself. This conclusion assumes that both: 1. FAA certifiers would have found something that the Boeing engineers did not. 2. The system was not modified for four years. #1 is debatable and hard to prove. And I doubt #2 is how things work in the real world.
