Being given control of the aircraft is secondary. You've condemned 200 odd people to death cause of one person on the flight. A small bomb, any thing to disrupt the flight will do that. (This is very easy as opposed to going to a theater or other urban crowded locations and staying alive long enough to take out that many people). The point being your only option is to lose everyone on the plane. Is that a casualty you're willing to accept. Security works by deterrence. If every time someone starts shooting in theaters and schools, the casualty is upwards of 200, its going to be a more viable option. Its a question of the cost of doing something vs the damage it causes. the inherent nature of flights (Since they fly), is that it takes relatively less effort to get one to crash. And it terms of preparation (in this ideal scenario as per this article), one guy just has to walk into a plane with items you get in your local store (propane maybe?). Im not an expert on this, but i just feel the effort required is just ridiculously easy if there is going to be no one to keep a tab on what you carry/have access to on a flight.
