Reminds me somehow on a mongrel between the Caproni Ca.60 and some Junkers projects
from the '20s and as an alteration to an old say:"Only the inventor can call this thing beautiful"
Technically feasible ? Why not , but I'm not an aeronautical engineer either. About the calculations
I'm not sure. For an aircraft such a thing probably is quite slow, for a freighter a containership usually
is quite fast, a "concordlifter" may be 6 to 8 times faster, than a containership, I think. And time en
route is just a part of the time to destination. And that it would be more direct, I'm honestly not sure,
because it would need completely new airports, I think, as it wouldn't fit standard runways and, probably
more important, wouldn't fit into standard flight procedures of standard airports. Today new airports usually
can only be build far away from population centres, so a more direct delivery is harder to achieve, than with
transport by ship, I'm afraid, not to mention the astronomical costs of that new infra structure.
