Catrax Inc. is a Washington corporation providing technical services. Current activities include software development (embedded realtime applications, digital signal processing, general software support) and aviation services (pilot services, A&P mechanic services, and small-scale development of specialized aircraft gadgets). I am Lytle Johnson, president and principal technician. I've been developing software for many years, primarily for embedded real-time applications with an occasional application for larger machines. My formal education is in engineering and applied mathematics. I've been doing aviation for even more years, starting with a 3rd place in Junior FAI Gas free-flight at the 1958 Nationals at Glenview Naval Air Station, Glenview, IL.

• North Star first flight. A wmv video, about 3.6Mb. Notice the HID wig-wag flashers. Landing was made with backpressure on the stick because the trim wheel became unscrewed in flight and had fallen on the floor, hence no more nose-up trim. Fixed before next flight.
• Utah spring 2007. Flying the Utah back country, complete with airstrip and camping pictures, not to mention the accompanying textual drivel.
• Awos is a little black cat that I found in a woodpile in McCall, ID in May 2003. He was a fuzzy tiny ball of fur that came hopping over to me on my bicycle and went home in my backpack.
• Floatplane trip, Fairbanks to Kenmore Air Harbor, late September 2003. Ice didn't melt off plane in Fairbanks til almost noon. Bad weather on Gulf coast. Nice day in Southeast. Stayed overnight at the New York hotel in Ketchikan, by way of Sitka. Headwind all the way.
