This is a Fantasy Ship with built in head wind. Suitable for slowly flying over a beautiful landscape except for the poor people on the upper deck who see the same sky as when they are at home sitting in their garden. Also little regard for weight.Cruise Ship in the Sky
We see people not boycotting United because it is cheaper. Time on board an airship need not be lost. You can look out at the landscape, but you can also work, much better than in a current airliner, or sleep with your wife. If you are in a hurry to contact someone on the other side of the World you wouldn't fly, not even by supersonic airliner - if you can pay for it, you would use internet. And I do believe that supersonic airliners will always be too expensive for the vast majority, even without carbon tax.being blunt For long range travel A fixed wing Aircraft is far more efficient in speed of travel ability to power through weather then a airship. You can try and say more fuel efficient and it is. but people looking to travel at ranges don't want to spend days on trips, unless the travel is the Trip. If you are a business Passenger in the 1930's a few days on the Hindenburg from Lakehurst to Frankford was a revolution in travel. Today No. Most people traveling don't have the luxury of time. Thats more a vacation/Tourist thing.
And the "environmental and Fuel efficiency" advantage would be tossed out if half the travel market is going supersonic.
as for Railways There are still parts of China, Japan and Europe without Rail. High speed Rail in the Americas is coming but like all things it has detractions.
I read the comments on the Australian site and the one serious objection to the V-tail was this one:
