Crash investigators in Cameroon have found one of the black box data recorders from the Kenya Airways plane which crashed on Saturday. It is thought the recorder may help determine the cause of the crash which is believed to have killed all 114 people on board, including five Britons. The investigation has so far concentrated on the theory that the jetliner lost power in both engines and tried to glide back to the airport before plunging into thick mangrove swamps 12 miles from Douala airport.
          The Nairobi-bound Boeing 737-800 sent a distress signal shortly after take-off and then lost contact 11 to 13 minutes later. It took more than 40 hours to find the wreckage, with most of it submerged in murky orange-brown water and hidden by a thick canopy of trees. Speaking on Monday at a news conference in Nairobi, Titus Naikuni, the chief executive officer of Kenya Airways, said there was no confirmed information regarding casualties or survivors, but added: "We will continue to provide confirmed information as we receive it."
          Debris at the crash site is spread over a small area roughly the size of a football field with much of it, including some hanging from trees, shredded beyond recognition. Workers have been carrying bodies and body parts on stretchers for the 20-minute hike through the swamp to ambulances parked as close as they could get. Officials were initially unable to locate the crash site because of an incorrect satellite signal, possibly emitted from the plane. But fishermen living in the swampy mangroves near Douala airport reported hearing a loud sound at the time of the crash. Kenya Airways is considered one of Africa's safest airlines with the Douala-Nairobi flight running several times a week.
