Personal Jet Prototype Joins Other Sonex/Monnett Aircraft

Sonex Aircraft announced that the JSX-1, the original SubSonex proof-of-concept personal jet prototype is now a resident of the EAA  Aviation Museum’s collection in Oshkosh, Wisconsin.

The historic aircraft joins the original prototype Sonex and other aircraft designed by John Monnett. The display will be reorganized and includes the Sonerai I prototype, the original Moni motorglider prototype, and the Monex racer.

The JSX-1, tail number N141SX, is the very first Sonex jet that flew in August 2011 at Wittman Regional Airport (KOSH) in Oshkosh with air show performer Bob Carlton at the controls. It was originally designed with a much lower-powered engine than the PBS TJ-100 that was eventually used. The JSX-1 also has a smaller cockpit, less fuel capacity, fixed main gear, and manually retractable nose gear compared to the Subsonex being built and flown around the world by the company’s customers. The JSX-1 was very successful during flight testing and led to the development of the JSX-2 aircraft.

Speaking in 2011 about the first flight of JSX-1, John Monnett, Subsonex designer and President of Sonex Aircraft said, “It’s an exciting day for Sonex. We have a test flight plan to expand the envelope of the aircraft, and we’ll see where the project takes us from here.”

And the rest, as they say, is history.
