John has mainly participated in model airplane activities as a competitor. He built his first model airplane in 1954 at the age of 9 as an avid free flighter and started flying control line speed to accumulate high point award credits. John set his first AMA national speed record and recorded his first AMA Nationals win (free flight) in 1960 at the age of 14. John has set AMA national records in free flight, control line and radio control categories and was crowned F3D R/C Pylon Racing World Champion with his life-long friend and flying partner Dub Jett. John and Dub are also the designers and developers of the DJS racing engines that were essentially never defeated.
Other interests include auto racing, model boats, travel, astronomy and telescopes.
John received an undergraduate degree in mechanical engineering and a graduate degree in electrical system engineering. John retired in 2008 as Senior Engineering Fellow and Chief Engineer with Raytheon.
