95% of the time a plane is already out of range of an RPG. 10k-30k feet up in the air is just too high. The only time it would be vulnerable to such a device is on takeoff or landing, even then, a 30 second delay means its already gone after you find anything out.
Even then, you wouldn't be a terrorist, you'd be an assassin, a terrorist only needs to know its a plane, with people on it. Airlines typically want to make money by having people on them, so anything with wings will do. And I'm sure they can tell the difference between a passenger plane and a cargo plane.
If you think about it, its all just plain stupid security theatre for political posturing. I hope they censure the MP for his idiocy. This reminds me of the bozo who was warning about the dangers of smoking LETTUCE.
