Another lesson in the futility of drug prohibition: Drug smugglers are using low-flying aircraft that look like motorized hang gliders to circumvent new fences along the U.S. border with Mexico. The planes, which began appearing in Arizona three years ago, are now turning up in remote parts of California and New Mexico. And in a new twist, the planes rarely touch the ground. Pilots simply pull levers that drop aluminum bins filled with about 200 pounds of marijuana for drivers who are waiting on the ground with blinking lights or glow-sticks. Within a few minutes, the pilots are back in Mexico. (Link to Story)
