It appears that most people on HN feel that TSA regulations are pointless theater and should be weakened or eliminated, while the FAA is to be blamed for not exercising their regulatory power strongly enough (especially in light of the 737 MAX).
Both agencies seem to follow a similar methodology: when there's an incident, analyze the cause and enact regulations that would have prevented it, building up a system leads to fewer incidents over time. And they seem to have led to similar results -- over the past decade, there has been only one passenger fatality on commercial flights within the US due to accidents, and zero due to hijackings/bombings.
Why the difference in opinion? Is it that TSA regulations are personally annoying to travelers while FAA regulations are mostly invisible to passengers?
