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.
