The bodies of three Americans who died when a water bombing plane crashed while battling Australia’s unprecedented wildfire crisis were retrieved on Saturday as their families arrived in Sydney, officials said.

Ian McBeth of Great Falls, Montana, Paul Clyde Hudson of Buckeye, Arizona, and Rick A. DeMorgan of Navarre, Florida, died when their C-130 Hercules tanker crashed on Thursday after dumping fire retardant on an out-of-control blaze northeast of the town of Cooma in southern New South Wales state.

Crash investigators have yet to explain why the four-propeller plane crashed in a fire ball shortly after dumping its load of water with additives in turbulent conditions. The plane was contracted from Canada-based Coulson Aviation, which is sending executives to Sydney.

Wildfires have claimed at least 33 lives in Australia since September, destroyed more than 3,000 homes and razed more than 10.6 million hectares (26 million acres). That's an area larger than the U.S state of Kentucky.
