You seem to be equating success with charging someone with crime and a harsh punishment. This is not the case. Success could simply be a bottle of volatile liquid thrown in the trash. Success could be an 'oops, someone forgot about ammo in their carry on luggage again'. Second point. It is no longer necessary for a terrorist to board the plane at all. Suicide bomber on a busy day at the security check point could kill far more than a plane load of passengers.
