the first trials are made you may have to pay for the experience, and not mind an arm or leg." This greater force would not become possible until the motor was invented. Technical description The image shows the flying machine from above looking down. It consists of one large wing. In the middle of it is a hole with a basket, where the pilot stands. There are two "paddles" on the wings. These are used by the pilot like oars in a boat, except in this case they only move up and down. Underneath the ship is the landing gear; it consists of four long poles, which, except for the ends of two, can not be seen since they are below the ship. In between them is a weight, which is used to keep the ship balanced. The wing is a light frame covered with strong canvas. The large wing would work as a glider, and by working the paddles up and down the pilot would keep the plane in the air, Swedenborg initially hoped. Legacy Swedenborg's machine was evaluated by the Royal Aeronautical Society in 1910. Its editor wrote that the machine constituted "…the first rational proposal for a flying machine of the aeroplance [heavier-than-air] type…" Later working heavier-than-air flying machines were built (e.g.Wright Brothers) so Swedenborg's machine did not play any part in the further development of aviation.” See also References History of aviation 1714 works Works by Emanuel Swedenborg 18th-century aviation
