SURABAYA, Indonesia (Reuters) - A sonar image showing a large, dark object under the sea was presumed to be the missing AirAsia plane, an official with Indonesia's search and rescue agency said on Wednesday. "It's about 30-50 metres under water," said the official, Hernanto. Crews are standing by to collect and identify bodies from the plane that crashed on Sunday during bad weather on a flight from Indonesia to Singapore. "We are praying it is the plane so the evacuation can be done quickly," Hernanto said. (Reporting by Gayatri Suroyo; writing by Michael Taylor; Editing by Robert Birsel)
