U.S. Army Sgt. Billman from the 5th Battallion, 5th Air Defence Artillery Regiment, 2nd Infantry Division, cheers after he shot down a drone airplane using a remote to control the 50 caliber machine gun in an Avenger weapons system during exercises at the Chul-mae firing range, 300 km (186 miles) south of Seoul, on March 4, 2003. Four North Korean fighter jets intercepted a U.S. Air Force RC-135 reconnaissance plane in international airspace over the Sea of Japan on Sunday and came within 50 feet of the big American jet while shadowing it, the Pentagon said on Monday.
