Swedenborg's 1714 airplane : a machine to fly in the air

Though better known for his theological writings, Swedish scientist and visionary Emanuel Swedenborg (1688-1772) was also an inventor who was extraordinarily ahead of his time. One of his early designs, circa 1714, was "a machine to fly in the air" -- anticipating the modern airplane by more than 150 years. With its oval, fixed "sail," Swedenborg's contribution soars above its predecessors with its simple, workable design.

Henry Soderberg encountered this remarkable invention while research for a book on the history of flight. In this account Soderberg offers an overview on the dream of flight through the centuries and places Swedenborg at a pivotal point in aviation history.
