Скачать или смотреть London’s Air Defence By Balloons In WWII - How?

First statement: balloons weren’t supposed to defend much, it was a jungle of steel cables hanging from them that weaved a net above London, crashing any plane trying to lower attitude for a more accurate bombing run.
Second statement: doubtlessly a couple of German planes did crash in that way, but the small number of balloons makes me question the validity of even bothering to make and maintain them, they must have served as a means to appease the population and boost morale.
Third statement: switch to night raids during the war and quick abandonment of diving runs that despite a much greater accuracy left bombers exposed to fighters coming from higher attitude and anti-aircraft guns, left the balloons ineffective in mere months after their first use.
