Have we not learned our lesson?
Safe, nonflammable helium!
We might not have enough helium for medical equipment, much less a fleet of airships. https://www.nbcnews.com/health/health-news/helium-shortage-doctors-are-worried-running-element-threaten-mris-rcna52978
Thank you, I was looking for this. Helium has important applications in science and medicine, and we cannot afford to use such large quantities for air travel. I'd much rather see development of modern sail ships, possibly in combination with fuel cells.
