Reminds me of Cargolifter, they tried something less ambitious and failed... but that was 20 years ago, at the very height of the dot com boom. Better luck to the Pathfinder 3 team! It would be amazing to see airships revived.https://en.wikipedia.org/wiki/Cargolifter

Cargolifter aimed for twice the size in all dimensions resulting in eight times the capacity, 160 tonnes as compared to 20 tonnes.
