If I had any money left I wouldn't invest it in this project.
The idea of carrying high-yield pax à la Orient Express has faded, not enough of them want to go that slow. Now we realise that freight schedule times can't be guaranteed, forget just-in-time delivery.
Furthermore those engines would be a maintenance cost nightmare, imagine the expense of a weeks flying (ONE transatlantic round-trip).
I wonder how many identical blimps would be built, for economy of scale. Sounds like bespoke tailoring. All the development cost to spread over a handful of machines.
Have these guys ever counted beans?
