British and United States coastguard officials have organised a search for a British man who fell off a yacht in the north Pacific.
An aircraft carrier belonging to the US Navy has diverted from its course home.
The USS Peleliu sent a helicopter to the area, hundreds of kilometres west of Midway Atoll, where it airlifted one British person off the yacht.
A military transport plane is helping with the search for the vessel's other crewmember.
Officials say the 35 year-old man who went overboard is wearing a yellow lifejacket with a light.
