In 1947 individuals were first allowed to build their own airplane and have it certificated for flight by the government. In 1953, Paul Poberezny founded the EAA. This began a movement that has endured through the present time. Many people began to enjoy actually building aircraft and then flying them. Believe me, in the early days it was truly aircraft building. Kits that simply needed to be assembled had not been developed. During the 1970's and 1980's several new designs came into being. Custom aircraft building started to become more and more popular.
