AlHijjah 15, 1432, Nov 11, 2011, SPA -- Federal officials are investigating the fiery crash of a tour helicopter that slammed into a mountain ridge on Hawaii's Molokai island, killing the pilot and the four tourists aboard. The aircraft carrying the five people was on a tourist excursion of West Maui and Molokai when it went down near an elementary school Thursday, AP quoted authorities as saying. Firefighters recovered four bodies and the fifth was located under the wreckage, Maui County spokesman Rod Antone said. There was no word on the cause of the crash but he said the Federal Aviation Administration and the National Transportation Safety Board were investigating. Blue Hawaiian Helicopters owner David Chevalier said the passengers were two men and two women taking a 45-minute tour that departed from Kahului, on Maui.
