This model of the Canadair CL-84 aircraft comes from Bombardier Aerospace. The idea was to design a prototype of a plane that could take off and land vertically. The plane was equipped with two propeller engines on its wing. The wing tilted upwards for vertical takeoff, and then returned to its horizontal position for conventional flight. Four prototypes were built, including one in Montreal, in 1969. The aircraft remained at the experimental stage. The CL-84 program ran from 1964 to 1972, logging 169 flight hours.
