Commercial flying is safer than ever, and the most prominent safety measures appear to be worthless. I have assumed that most of what the TSA does is worthless, but I thought that securing the cockpit doors was valuable. Now it appears to have caused the Germanwings crash, as well as a 2005 crash. I haven't heard that it has saved anyone.
Every time you fly, they tell you about emergency oxygen masks and flotation seats, even tho these never save anyone. The oxygen even caused a 1996 Florida crash.
The airline industry would probably justify this stuff by saying that the public needs a big show of safety and security in order to be convinced to fly. That seems crazy to me. The safety record is already so good that your drive to the airport is more dangerous than the flight. We should abolish the TSA and let the airlines just do what really contributes to safety.
