Actually, if they're properly fireproofed, lighter-than-air aircraft are far more cost-efficient than any winged aircraft in transporting non-time-critical cargoes. They can't compete with aeroplanes for speed but they can carry much heavier loads over much longer distances per unit fuel loaded. Using Helium instead of Hydrogen as a lift gas renders modern airships almost totally safe from fire.

FWIW, if someone wanted to invest in it, I could see Hindenberg-sized airships returning as the cruise-liners of the skies.
