On its long slender wings, the U-2 Dragon Lady flies high -- it can go up past 70,000 feet, or about 13 miles -- and over the years has packed an ever more sophisticated variety of cameras and sensors. In all, just over 100 U-2 aircraft were built up through 1989, and a number of them, like the contemporary one seen here, are still flying today, not yet put out of commission by 21st-century drones.
