During the past two decades, McGraw, an engineer at Lockheed Martin in Sunnyvale and a San Jose resident, has set five of the six world records for flying the most number of kites at once.   And on Oct. 4 at the Air Force Museum at Wright-Patterson Air Force Base in Dayton, Ohio, McGraw set a new mark for the Guinness Book of World Records by flying 230 kites at a time — in a train 192 feet long.
   Oh, yea, an unidentified sidekick was with him.
