> Either that's a smaller airship than his articles describe, or it's just artist's discretion. They always talk about 500 ton cargo ships - as in "delivering 500 tons of cargo". From their images, the airship is about 30 containers long. That's only 600 feet, shorter than the Macon or the Hindenburg. Useful lift of the Hindenburg was 232,000 kg.
