The depicted images didn't show a ground-effect vehicle, which seems odd -- it fits the job and is much more economical than the winged plane shown.

There's the mention of "sustained flight at mid-altitudes". Perhaps the intention is for this to be able to fly over land as well? Maybe by sacrificing some cargo capacity in mid-altitude flights?

I wasn't aware of that pattern.

Can you give some examples of Americans doing this more than other peoples?

> doing this more than other peoples

I don’t think a pattern needs to be exceptional to be notable.

The first example that comes to mind is Freedom Fries (lol) https://www.google.com/search?q=freedom+fries&ie=UTF-8&oe=UT...
