The Vickers Transoceanic Airship project was a planned airship series around the 1930s to design and mass produce GIANT, 800 ft. Rigid airships, or Zeppelins.
The design of the cruise ship.
These planned ships would have Space for over 70 passengers. Unfortunately, The Hindenburg disaster and the company making this, Vickers, had money issues anyway, which ultimately halted production.
The ships would include a deck on the top of the ship for sightseeing. This was originally going to be included on the hindenburg, but wasn't for unknown reasons..
