Danilewsky Pilstrem
![]() The second man-powered airship constructed by Dr. Konstantin I. Danilewsky of Charkov, Russia (now Ukraine). Supported by industrialist A. A. Pilstrem, and flown by the 20-year old engineer-aeronaut Peter Koziakov it made its first ascent on 18 June 1898. It was controlled by fans, or wings, up to 16' 4" long, which could be opened over an arc of 90 degrees. It was trial-flown with some success, making several ascents in alternate configurations, and demonstrated before a Russian board of inspection on 15 August 1898.
