The problem with this is, if you shoot and miss, the bullet goes somewhere. Airports are near cities, and there tend to be people "down range".

nah most airports ain't. not all of em mind you, but usually you keep people away

these projectiles aren't going to travel 9km unless you're shooting off SAMs or other serious AA

i'd be more worried about FOD on the runways getting sucked into an engine or popping the tires of service vehicles
