None of this number crunching is occurring in a vacuum. As a matter of fact, the International Civil Aviation Organization protocol for accident investigation is being followed just as it would in the United States. At the request of the Malaysian government, the Australian Transportation Safety Bureau has been leading the search. As parties to the investigation the Malaysians have included Boeing, the National Transportation Safety Board, the Air Accidents Investigation Branch of the U.K., the Defence Science and Technology Organisation of Australia, the Malaysian Department of Civilian Aviation, Inmarsat and the U.K. division of Thales Corporation. More parties may be included once the 777 is located.
