US safety officials say a team of experts is en route to Asia to be ready to assist in the investigation of a Malaysia Airlines jetliner that disappeared with 239 people on board.
The team includes accident investigators from National Transportation Safety Board, as well as technical experts from the Federal Aviation Administration and Boeing.
The Boeing 777-200 went missing on a flight from Kuala Lumpur to Beijing early yesterday.
The safety board said the team has been sent already because of the travel time involved even though the plane has not yet been found.
The board said that once the plane is found, International Civil Aviation Organisation protocols will determine which country will lead the investigation.
