I've heard that as well; very interesting. I don't now how close any of the designs are to production. That could be a lot cheaper than building a whole lotta C-17's for lift we seem to need once a decade.
My experience is now a bit dated, but when I was involved in load planning I was told to forget ever being deployed by air in an emergency (except units flying to prepositioned equipment) because the Air Force would tie up almost all the lift initially in transporting their own equipment to forward bases.
