Re: Why the fins

They ensure that the balloon is always facing into the wind.

Why the fins?

Why does a barrage balloon need tailfins? It appears that it will be moored to maintain a certain orientation, so tail fins would only act to make it move from that orientation whenever the wind was blowing in a different direction.
