High wing IS conventional ... for military transport.
With the wings on top, they may be able to use even higher bypass ratios without doing stupid things like making oval intakes.
This may well be a good idea. The wing loading will be much higher than has historically been normal for commercial aircraft. They’ll have to account for that in both design and maintenance.
“Net zero” is just bullcrap.
Yeah, those skinny wings just scream “overload me!”
