U.S. aviation experts conferred with their Kenyan and Cameroonian counterparts Wednesday in an effort to determine what caused a Kenya Airways jet to crash into a central African swamp, killing all 114 people on board. A team from the U.S. National Transportation Safety Board was meeting with the African experts, said Lonnie Kelley, the U.S. Embassy spokesman in Cameroon. British experts and officials from Boeing, which made the 737-800 that crashed Saturday, also were expected to arrive later Wednesday.
          Kenya Airways chairman Evanson Mwaniki said his company was bringing in British forensic and DNA specialists and equipment to help identify bodies. Bodies were being found in pieces and badly decomposed after more than 40 hours in the water, making the "identification process more complicated and time consuming," Mwaniki said. Kenya Airways officials said Wednesday that the remains of 81 of those aboard had been recovered so far.
          The airline's chief pilot, James Ouma, told a Nairobi news conference on Tuesday that Kenyan crash investigators at the site now believe Flight 507 crashed about 30 seconds after takeoff. Officials in Cameroon had said earlier that they lost contact with the aircraft 11-13 minutes into the flight, but as their investigation continued, they appeared less sure of the timing on Wednesday. Questions have arisen as to when a distress signal believed emitted by the plane was sent — or whether it was even from the plane.
