Sydney: A new scan of the Indian Ocean floor for Malaysia Airlines Flight 370 has searched nearly 80,000 square kilometers since January without finding any sign of the wreckage. But the company looking for the plane, which has been missing for more than four years, said it is still determined to find it. This comes despite earlier hopes that a 25,000-square-kilometer area most likely to contain the missing aircraft had been identified. Ocean Infinity, the American technology company conducting the latest search, said in an update on Tuesday that it had scanned up to 1,300 square kilometers per day since launching its mission far off the west coast of Australia in late January. It has searched both inside and outside an area identified by Australian authorities.
