The Lockheed U-2 was designed to keep tabs on the Soviet Union over half a century ago. The RQ-4 Global Hawk drone was designed to replace this 50s antique. But how strange you are, fate! The U-2's replacing its successor.

I keep forgetting about how damn huge some drones are. Most people think they are tiny, like toy planes. As this photo of a Northrop Grumman RQ-4 Global Hawk shows, they are actually big. Big as in pretty damn huge.
