Once upon a time in the massive number of clicks across the web…
I recall going stumbling upon a diagram of a dirigible (IIRC) in whose tail fins were inflated by a ram air type opening- so more of a parachute than balloon.
The obvious problem being the induced drag of the opening versus the reduction benefit of such a mechanism.
Materials wise it doesn't seem (on the surface at least) much more difficult than a little plastic, parachute type nylon, and a needle and thread.
Anyone seen similar or heard of such?

Reason: grammar
