SubSonex Serial #21 (N958PD) made its first flight out of the Dayton Valley Airpark in Nevada on the 24th of March, 2019. Winter kept trying to hang on in the Sierra Nevada mountains, but the weather smiled on us, I had a great crew that made themselves available on short notice, and we got "Loki" off the ground for the first time. Thanks to all, and especially chase pilot extraordinaire Bob Mills, and my wife, Louise Hose, who acted as the airborne test conductor.

The build took about four months, in total, including paint (executed by airbrush master John Stahr) - a scheme which honors my years in the space program. Overall, the kit quality was high, and very complete - especially for such an early serial number - which made the build go quickly. The PBS TJ100 engine operated flawlessly on every test run and on the first flight, and the MGL avionics package that was custom-tailored to the jet has performed without issues.

In addition to my wife, I want to thank the neighbors at Dayton Valley Airpark who helped out when I needed extra hands, and the folks at Sonex Aircraft who facilitated the build with quick answers to questions along the way. We anticipate an interesting and fun Phase 1 test period.

  1. Make sure you keep your shit in check when flying around here, we've got enough problems with people thinking this area is a free-for-all, already.
