KUALA LUMPUR, Malaysia — Australian officials shifted their search for the missing Malaysian jetliner by nearly 700 miles, citing "a new credible lead'' about the path of the aircraft and where debris may be located.
Martin Dolan, chief commissioner of the Australian Air Transport Safety Bureau, said a revised analysis of radar data prompted the agency to refocus the search in the Indian Ocean off Perth. The analysis indicates that the plane was flying faster than previously estimated between the South China Sea and the Strait of Malacca before radar contact was lost, Dolan said.
Based on that new speed data, analysts calculated increased fuel usage and a reduced distance the aircraft could have covered with power.
The new search area is approximately 198,000 square miles in size and 1,150 miles west of Perth, John Young, manager of the Australian Maritime Safety Authority's emergency response division said. The move, about 685 miles to the northeast of the previous search area, was based on updated advice from an international investigation team working with the search, Young said.
The new location is also based on an assessment by Australian experts, the United States Coast Guard and commercial companies that took into account the weather and the drift any wreckage would be expected to have taken in the 21 days since the plane went missing.
All of these calculations are best estimates and, "will remain a somewhat inexact science," Dolan cautioned.
