Sonex is proud to announce that SubSonex JSX-1, the original proof-of-concept SubSonex Personal Jet prototype, has become part of the EAA Aviation Museum collection in Oshkosh, WI. Delivered to EAA last week, the historic prototype will join the original prototype Sonex and other John Monnett designs including the original Sonerai I prototype, the original Moni motorglider prototype, and the Monex Racer in the EAA collection. The JSX-1 will be displayed with these other Sonex/Monnett aircraft in a reorganized display, according to EAA.

Achieving first flight in August, 2011 JSX-1 N141SJ is the very-first Sonex jet to fly. Originally designed to use a turbojet with much-less thrust than the 258 lbf. thrust PBS TJ-100 engine that was ultimately selected for the SubSonex, JSX-1 has a fixed main gear, manually retracting nose gear, smaller cockpit and less fuel capacity than the current JSX-2 that is currently being built and flown by SubSonex customers around the world. This proof-of-concept vehicle proved to be incredibly successful in flight test, leading to the development of the current JSX-2 aircraft. You can read more about this history of the SubSonex design including the development of the JSX-1 prototype and the current JSX-2 aircraft kit in the SubSonex Development Archive.
