We are contemplating 16 million airships carrying 40 tons each - 0.64
billion dead weight tons - having a cycle time of 2.25 days delivering
delivering 140 billion tons of cargo per year - with far greater
flexibility than is possible with sea going ships. *If the same $22

represents?

Right for now it seems "We" = William Mook
