The airport checkpoints is why I won't fly. The odds of another 9/11 or even a similar incidence is so incredibly remote that the odds are unfathomable. It's nothing short of a feel-good proposition to have all this Government Employeed Security. Just like having firewalls & passwords on your computer, if someone wants in, they'll get in, no matter the precautions. 3 or 4 trained individuals could highjack an aircraft without any weapons. Those that have them have a false sense of security. Since that day, there will be civilians/passengers ready to put a stop to it.
Relax, take a flight, lay on a tropical beach with a Mai-Tai & a hooker & have fun...it can only get worse.
