PKZ-2 On June 10, 1918 the PKZ-2 was demonstrated for military commanding officers; two flights were made with observers in the basket, but others were made without an observer. On the same day the helicopter crashed from height and was slightly damaged. Military command refused the PKZ-2, saying it represented a "high danger to the observer". On June 21st the project was cancelled. PKZ-2_Observation_Helicopter_1918_1:48_Model
