This book describes the Petroczy-Karman-Zurovec PKZ-2 helicopter, an amazing WWI design which was so far ahead of its time but remained in comparative obscurity until recent years. Although never deployed operationally, the PKZ-2 made three dozen test flights before it was officially rejected following a disastrous crash on June 10 1918.
