When they introduced Light-Sport Aircraft FAA prohibited use of a jet engine. Looking at the photos nearby you can see that this airplane cannot pass must as a LSA. Or, wait! That’s no jet. It just pretended to be one at Aero Friedrichshafen 2016. At my home airport (Spruce Creek Fly-in), I regularly see one or another full-size L-39 in various stages of being prepared for a new American owner. I was told that about 200 of these ex-Czech military jets are operating in the U.S. They are handsome, sleek, and fast-like-a-jet. Contrarily, the UL-39 is not as fast but neither should its cost of upkeep be anything close to a military jet. We’re getting a bit ahead of ourselves. The UL-39 on display was a wonderful proof-of-concept aircraft that managed to engage nearly a generation of students in aeronautical engineering disciplines at the Czech Technical University in Prague.
