Initial reports have not been encouraging.
Right. We all have heard about the numerous planes crashed into the ground because of the pilots undergoing divorces and having emotional problems.
If we trust them to fly the planes, we can trust them to defend the cockpit.
Its not a trust issue. Its an issue of spending a ton of money on a program that is voluntary and creates a semi-federalized private employee classification while accomplishing nothing.
If you want pilots to defend the cockpit you will have to seal them in like tuna in a can because trained attackers will overrun them whether they are armed or not if they can access them. They can still access them, BTW.
