This camera was installed on the military drone "L'Epervier" built at the request of NATO by the Belgian firm M.B.L.E. This unmanned reconnaissance aircraft was remote-controlled from the ground. Not equipped with a landing gear, he took off from a launching ramp and landed with his parachute.
The camera's installation flap was under the aircraft. "l'Epervier" (30 copies) was in operation from 1976 to 1999.
