What is a missile? What does “shoot down” mean?
Shooting down a missile is non trivial and mostly doesn’t happen. By anyone.
The problems of radar cross sectional area plus velocities plus short range at initial detection render most attempts silly.
People often don’t realize what happens. Missiles are often ballistic, meaning they are no longer propelled. They were launched, used up their fuel and then coasted (not flew, coasted) to the target.
What would “Shooting down” mean for such a missile? It was headed down anyway. If you hit it, you would hope for what? Disable the warhead? That means when it hits the ground you don’t think the warhead will explode?
Understand that the media knows nothing.
Journalist degrees don’t require Science classes beyond a public high school comprehension.
