Also, while it says it would slow the planes down -- that was just one idea -- in reality the wire actually sliced into wings and vital parts and in some cases caused massive damage.
If I recall they had some designs where the baloon detached when the wire was hit, and at the baloon was a small mine charge. As the wire ripped downward into the fast-moving wing (being anchored in place) the mine charge would hit the wing and explode.
In AH I could see them as indestructible items. Like trees. You hit 'em, you lose a wing. Kind of like in real life. This idea would be easily done with what we have now (no need to recode AH, just use custom models on the terrain).
Now, making the baloons destructible.. that's another problem... Plus when one is shot down it can be raised again by the ground crew.
