Pilot radioed in 'Mayday' call before Australian plane crash

A pilot repeatedly yelled out "Mayday" but did not say what the emergency was before his light plane crashed into the roof of an Australian shopping mall, killing himself and four American tourists, an accident investigator said Wednesday.

Police blamed "catastrophic engine failure" when a twin-engine Beechcraft B200 Super King Air crashed into the Direct Factory Outlet mall in the Melbourne suburb of Essendon on Tuesday moments after takeoff from a nearby runway.

Ancient urban networks around Angkor Wat discovered

An Australian archaeologist says he and colleagues have found evidence of previously undiscovered medieval urban and agricultural networks surrounding the ancient city of Angkor Wat.

Using high-tech lasers to scan the Cambodian jungle, Damian Evans and colleagues say they found traces of extensive networks surrounding the monumental stone temple complex at Angkor Wat. Evans said their findings could further our understanding of Khmer culture and throw into question traditional assumptions about the 15th-century decline of the empire.

Assange to accept arrest if UN panel rules against him

WikiLeaks founder Julian Assange says he will accept arrest by British police if a U.N. working group investigating his claims decides that the three years he has spent inside the Ecuadorean Embassy doesn't amount to illegal detention.

Writing on WikiLeaks' Twitter account, Assange said if the U.N. panel finds he has lost his case against the United Kingdom and Sweden then he will turn himself in to police at noon on Friday.
