To date, most airships have been cigar-shaped. This shape may be sensible for the scheduled transporting of regular cargo from airfield to airfield, but is not ideal for ad-hoc airlifting from any-site to any-site.

And the airship must hold position in variable wind conditions and with minimal ground infrastructure.
