Here is something that you don’t get to see every day, its small jet plane from Sonex Aircraft. this is one of those projects that could quite easily take over your life. But at the end of it you get a cool jet powered plane to fly around in and that is really something special.
According to the Sonex Aircraft website, this is current status of the SubSonex JSX-2 prototype;
The Hornets’ Nest R&D Team at Sonex Aircraft, LLC are continuing to progress in the design of the SubSonex JSX-2 prototype. JSX-2 will be a more “conforming” prototype to what a SubSonex VVLJ (Very, Very Light Jet) kit aircraft product would consist of, and will include many advanced features and improvements.
This plane in a box is supposed to be comparable in price to a light sporting aircraft.
