But even this interior piece is also unlikely to prove very helpful to investigators, said Dell, the accident investigation expert. As for the underwater search, crews have combed more than 105,000 square kilometers (40,000 square miles) of the Indian Ocean to no avail. In March, investigators confirmed two pieces of debris found along Mozambique's coast were almost certainly from the aircraft. Malaysia's government said Thursday that two more pieces of debris, discovered in South Africa and Rodrigues Island off Mauritius, are "almost certainly" from Flight 370, bringing the total number of pieces believed to have come from the missing Malaysian jet to five. All five pieces have been found in various spots around the Indian Ocean.
