From the Associated Press:
The glider-like plane with a single-seat gondola and a 31 meter (102 feet) wingspan was powered by 160 AA "Oxyride" batteries which have been produced by Japan's Matsushita Electric Industrial Co. since April 2004.
It soared as high as 5.2 meters, stayed in the air for 59 seconds and covered a distance of 391 meters (428 yards) at a private airport owned by Honda Motor Co.
