Return of the barrage balloons?

One of the blogs i read regularly is Eagle Speak, especially the weekly "Sunday Ship History" which is a historical retrospective. Earlier in the world it was on the use of barrage balloons for anti-aircraft defence.

A good read as always but at the end i noticed with interest in the late 1980s it was suggested by the USAF to use barrage balloons to stop enemy aircraft from flying too low to evade anti-aircraft defences.

That was something i didn't realise about barrage balloons, they were not really intended to trap aircraft with their wires (though it was a bonus if they did) but it was to force the enemy aircraft to fly higher to make them more vulnerable to AA fire and compromise their ability to carry out their attacks.
