At one level this is essentially a home-built, done by a guy who got others to help pay for it and who organized a bunch of worker and engineers to get it done. This is a large accomplishment even if, technology wise it's not entirely new. Show of hands among those who built a multi-billion dollar company because they wanted a plane that no one else would build for them. This was literally the reason given by the Wright brothers; that in spite of all the announcements, no one had a plane for sale and they wanted one.
I don't share their vision that this will end up in commercial service as I am unsure if the regulatory agencies are looking for another window-banging take-off screamer operating out of civilian airports.
I am intrigued by the claim they were contracted to build a version for use as Air Force One.
