Firefighters in Australia held a minute’s silence on Friday for three U.S. colleagues killed in a plane crash as investigators began scouring the accident site in remote bushland.
The premier of New South Wales (NSW) state, where the C-130 Hercules crashed while on a mission to dump retardant on a huge wildfire, ordered that flags on official buildings be flown at half-mast as a mark of respect.
“We will forever be indebted to the enormous contribution and indeed the ultimate sacrifice that’s been paid as a result of these extraordinary individuals doing a remarkable job,” NSW Rural Fire Service Commissioner Shane Fitzsimmons said at a farewell near Sydney airport for 32 U.S. firefighters who were returning home after weeks on duty on Australia.
Fitzsimmons and air safety officials said it was too early to speculate on the cause of the crash.
“We simply don’t know the circumstances pertaining to the accident at this stage,” Fitzsimmons said. “Appropriate, formal investigations and inquiries are underway.”
The three crew who died were Ian McBeth, 44, Paul Hudson, 42, and Rick DeMorgan Jr., 43, their employer, Canadian firm Coulson Aviation said in a statement. All three had previously worked for the U.S. military. Two were married and two left behind young children.
“We honor the amazing crews who do incredible things in dangerous circumstances supported by world-class operations,” Coulson Aviation said in a statement.
The company had grounded its other air tankers in Australia immediately after the crash on Thursday but said they would be returning to work “in the very near future”.
Fitzsimmons earlier said field reports showed there had been a “pretty significant fireball associated with the plane crash”, while a spokesman for Australia’s Civil Aviation Safety Authority told Reuters the aircraft went into a valley to drop the retardant and did not emerge.
The Australian Transport Safety Bureau said it would provide a preliminary report in about 30 days, after analyzing available recorded data, reviewing weather information and interviewing any witnesses.
The owner of the aircraft, Canadian aerial firefighting company Coulson Aviation, was sending a team to help with the investigation. They are due to arrive in Sydney on Saturday morning, Fitzsimmons said.
A U.S. National Transportation Safety Board official said the agency plans to have some involvement and will likely send an investigator or two to Australia.
There have been two previous crashes involving C-130 Hercules aircraft while fighting wildfires. In a 2002 accident in California, caught on video tape, the wings of the plane folded upward, breaking off the plane before the fuselage rolled and hit the ground upside down, killing all three crew. In 2012, another C-130 crashed in South Dakota, killing four of the six crew, in an accident that was later determined to be weather-related.
“Unfortunately, aircraft are one of the riskiest parts of wildland firefighting,” said Eric Kennedy, a disaster and emergency management expert at York University in Toronto, Canada.
Kennedy said there many possible causes for Thursday’s crash, but noted that a well-known risk in the C-130 fleet was metal fatigue-induced wing failure.
“Reduced visibility, high turbulence, and low flying can all be contributing risk factors for air tanker crashes,” Kennedy said in emailed comments.
SMOKE HAZE RETURNS
The plane crash on Thursday took the death toll for Australia’s devastating bushfire season to 32, including eight firefighters. The wildfires have also killed millions of animals, razed thousands of homes and destroyed a land area about one-third the size of Germany since September.
Six local volunteer firefighters were injured later on Thursday when a water tanker vehicle rolled when they were battling a blaze in the south coast region of the state. Three were released from hospital on Thursday night, while the other three would be released on Friday, officials said.
While fire conditions eased in southeastern Australia on Friday, Sydney was choking on a new smoke haze, blown in by a baking hot wind from the fires burning in the south of the state. The harborside city was also covered in a layer of terracotta-colored soil brought in from the west by huge dust storms.
In New South Wales, firefighters were tackling 95 blazes, but they were all at the lowest warning levels. In Victoria state, one out of 60 fires was rated at the warning level of “watch and act”, meaning there was no immediate danger.
