I'm curious why barrage balloon techniques aren't being utilized to
protect against terror attacks from the air. A well-engineered
network of modern balloons should improve the likelihood of diverting
all but the largest commercial aircraft from U.S. point targets vice
an Avenger salvo, and balloons have many advantages. Large caliber,
rapid-firing artillery such as an upgraded Skysweeper could further
contribute. Views?

There's the annoying little problem of said efforts causing a hostile
aircraft to land on populated areas when employed in a large city. Not much
point in say stopping a jetliner from hitting the Empire State building if
it falls into the streets of New York and kills thousands of people on the
ground.
