Key Takeaways:

  • Redge Greenberg, an experienced pilot, successfully completed the first customer-assembled SubSonex jet (JSX0003) and performed its initial flight.
  • He assembled the jet from an "ultra-quick-build" kit, which minimizes customer work to installing key components like the engine, fuel system, and avionics.
  • Greenberg's SubSonex is only the third of its kind flying worldwide, allowing him to fulfill his long-held ambition to pilot a jet.
  • The SubSonex ultra-quick-build kit, including the PBS TJ-100 turbojet engine, is priced at $135,000.
