Recalling a Good Pilot Friend and One Curious Character

Key Takeaways:

  • John Roncz was a pioneering computational aerodynamicist who revolutionized airfoil design for Burt Rutan and other significant aviation projects, including the Voyager and Beech Starship, using early computer simulations.
  • He made extensive and diverse contributions to aircraft design, creating specialized airfoils, complete airplanes, and various other aerodynamic components, often named with a quirky sense of humor.
  • Roncz led a strikingly dual life, balancing his highly analytical engineering career with a deep and acknowledged engagement as a practicing psychic medium, an incongruity he explored in his book, "An Engineer’s Guide to the Spirit World."

It’s long ago now—more than four decades back, during a time when I would fly to Mojave every week in Melmoth to have lunch with Burt Rutan and his then tiny group of employees. From a dilapidated barracks there, RAF, the Rutan Aircraft Factory, sold plans of the novel canard VariEze to amateur builders.

RAF started in the pre-digital age, when the tools of the aeronautical engineer were still slide rule and drafting paper. Around 1980, however, Rutan bought an Apple 2 computer. When the salesman asked him whether he would like a second 160 kilobyte floppy disk in addition to the one supplied with the computer, he declined it, saying that he would certainly never fill even the first disk. Some time later he proudly showed me a Corvus hard drive for which he had paid thousands of dollars. It had the unimaginably vast capacity of 10 megabytes.

Peter Garrison

Peter Garrison taught himself to use a slide rule and tin snips, built an airplane in his backyard, and flew it to Japan. He began contributing to FLYING in 1968, and he continues to share his columns, ""Technicalities"" and ""Aftermath,"" with FLYING readers.
