The visiting British pilots were training near a naval air station one night this month when their helicopter came within about 150 feet of an ultralight plane flying without lights. The ultralight darted away toward Mexico without a trace. The near-disaster over the Southern California desert was an example of drug smugglers 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. "It's like dropping a bomb from an aircraft," said Jeffrey Calhoon, chief of the Border Patrol's El Centro sector, which stretches through alfalfa farms, desert scrub and sand dunes in southeast California. The Border Patrol has erected hundreds of miles of fences and vehicle barriers along the border and added thousands of new agents, so drug smugglers are going over, under and around.
