None of the problems we've seen lately are things that someone just didnt forsee happening over the course of years. It was simply a failure to properly install or inspect fairly simple parts of the plane. While I agree that these are complex machines with many moving parts, these were not complex failures. They should have Never happened and are completely unacceptable.
