As an infamous hoarder of aircraft design and construction books I naturally purchased all of the design and construction books on her site. They're self-published but very well done with lots of illustrations, and most importantly appear to be full of accurate and useful information. Her "Homebuilt Aerodynamics and Flight Testing" is the only flight test book I've run across that also covers flight-testing sailplanes. Her "Composite Facts" book goes over her inexpensive "cast it in a huge sand mold" technique (among numerous other topics). Her biography is on the final page of her book: born in Germany, interned in high school in a glider factory, aeronautical engineering degree, eventually ending up on the Adam A500 project and the Columbia 400. Now consults. Definitely seems to know her stuff.
