purilennuki
Purilennuki is a term originating from Estonian that describes a type of small, often improvised, aircraft. Literally translated, "purilennuki" means "glider." Historically, this term has been used to refer to simple gliders constructed from readily available materials, such as wood, fabric, and bamboo. These were often built by hobbyists or enthusiasts for recreational flying or as experimental craft. The design of a purilennuki can vary widely, but they typically share a common characteristic of being lightweight and designed for unpowered flight.
While the term is rooted in traditional gliding, it can also encompass more modern, lightweight powered aircraft
