<p>CIA developed the D-21 Drone for surveillance missions over enemy territory. It was launched from a modified A-12. The D-21's engine propelled it to speeds over 2,000 mph. During missions, the D-21 would follow a pre-programmed flight path over areas of interest and take pictures.  Then the drone returned to international airspace where it dropped the film canister. A specially equipped aircraft recovered the film canister. The drone would then self-destruct.
