A missile would need to fly all the way over Europe before reaching London. It would be noticed, jets would be scrambled and it would be shot. Just like what happened here.

These were ballistic missiles. They are only vulnerable during the terminal phase, when they are moving at hypersonic speeds. Standard fighter jets aren't going to do it. It would take ground based THAAD, Patriot, or ship based Aegis systems. London might want to budget for that.

They can fly well above any commercial and military aircraft.
