I'm absolutely fascinated by airships and would love to see them roam the skies again, but last time I looked at it they had too many drawbacks: - they are very sensitive to the weather condition, especially winds - they are more economical in fuel compared to airplanes but maybe not enough to compensate for their slowness - they use either hydrogen which is very dangerous or helium which is available in limited amount (and afaik already in tension)
