What sort of comparison is that the concorde was flying from 1976, the Hindenburg disaster was in 1937. You say can't work is a good compression of not economically feasible and you come to the economically feasible by comparing 1937 tech/economics with 1976 one? For comparison a commercial plane service didn't even exist for airfoil planes in 1937. So by your argument it was impossible to fly across the Atlantic (it wasn't actually, people had done it but your argument is uneconomical=impossible) , but nowhere close to bringing 100 passengers across.
