澳洲一架飞机在灭火时坠毁 飞行员丧生
A plane fighting bushfires in the Australian state of New South Wales has crashed, killing its pilot.
澳大利亚新南威尔士州的一架飞机在对抗森林大火的时候坠毁，飞行员丧生。
The water-bombing plane crashed near Ulladulla, south of Sydney.
Meanwhile the military said it was co-operating with a fire services probe that found an exercise using live ordnance（军火，大炮） started the State Mine fire.
NSW has been battling bushfires for days, amid high temperatures.
Officials have yet to release the identity of the pilot, who was the only person aboard the aircraft. His family has been informed of his death.
'No intention'
Thousands of firefighters have been mobilised to tackle the fires, and on Wednesday the state came through what officials had said would be a very dangerous day because of weather conditions.
Thursday brought cooler weather but more than 60 fires are still burning. Worst-hit has been the Blue Mountains area, to the west of Sydney, where many homes have been destroyed and some residents evacuated.
The State Mine blaze, near the Blue Mountains town of Lithgow, was seen as a serious cause for concern earlier in the week.
NSW Rural Fire Service chief Shane Fitzsimmons said an investigation had found it was ignited by live ordnance.
"It wasn't deliberate, it was a side-effect of a routine activity ... and clearly there was no intention to see fire start up and run as a result of that activity," he said.
Acting Defence Minister George Brandis said the military "take this issue very seriously and continue to fully co-operate with the NSW authorities, including the NSW Police, who are investigating the fire".
Blue Mountains Mayor Mark Greenhill said the military should have known better.
"I would have hoped on a day like that which was a dry day, a hot day, with the winds, the Australian military would have known it wasn't a good time to be igniting.
So far the NSW fires have destroyed more than 200 homes and left one man dead.
