HONOLULU, Hawaii (10 Feb 2001) -- Nine Japanese people are still missing following Friday's collision between the USS Greeneville and the Ehime Maru, 14km off Honolulu, Hawaii.
The Ehime Maru was halfway through a marine studies training voyage for Japanese students and teachers. Four high school students, two teachers and three crew are missing and feared drowned.
According to US Navy officials, the nuclear-powered submarine struck and sank a Japanese trawler during an emergency surfacing drill.
