Should someone be stupid enough to hijack a plane ever again, I don't think there's a government in the world that would hesitate in shooting down the plane anymore. At the very least, you'd get an escort of fighter planes.

And that's if you weren't jumped on by half the people on the plane the moment you tried it. Travelers don't assume they might survive a hijacking any more.
What drives me mad about the ongoing obsession over airplane security is the apparent assumption that terrorists can't figure this out. Being the bad guys doesn't mean being stupid in the non-cinematic world.
