Well, that's my theory at least...
So I recently see this piece in Wired News: "DIY Jets Ready to Resume Testing." http://www.wired.com/autopia/2010/09/diy-jet-ready-to-resume-testing/
As mentioned in the piece, the guys at Sonex appear to be going some way towards eliminating "one of the main complaints of many pilots and would-be pilots, the cost of buying a fun to fly airplane.
(Me, I'm thinking "fun-to-fly" as in the Sonex "SubSonex" Jet, not so much the prop-driven "One-X, " also shown)
Anyway, the "DIY Jet" discussed made me recall certain points near of the end of the first remotepilot.com piece I wrote: "What Are the Live Drivers Going to Do?" http://www.remotepilot.com/2009/06/manned-military-fighterattack-jet-air-craft-go-civilian.html
Well again, I'd submit that if perhaps some military combat fighter/attack jets get displaced over the battlefield by UAVs, that single or two seat Jet aircraft pilots will hardly go the way of the dodo.
Instead, some may find new opportunity as the new civilian "race car drivers of the sky." And who knows, aerial "dog-fighting" as motorsport ("air sport") may become a civilian pastime in a few decades, with ESPN coverage and purses in the millions.
I speculate that the more the Military Employs UAVs, the more you'll see civilians Interested in owning recreational jet aircraft.
I think the Wired piece shows that the guys at Sonex and perhaps other manufacturers are aware that there is potentially this strange new market for recreational jets out there.
