I have a Der Jager project that I am about to start working on. A couple of questions have come up and there does not seem to be much history and no live contacts. The plans were bought in 1972 (#184) and sold at least 3 times since. We have been able to figure out that the plane was registered in 1990 and deregistered (destroyed) in 1996. Many components including the fuselage are complete.First question: Does anyone know how to contact the Designer, Marshall White, who was from Anaheim CA or his successor? There are statements like "plans cannot be sold without permission of the designer."Second question: Because destroyed planes cannot be resurected, any suggestions on how to proceed?
