The Royal Australian Air Force will conduct flypasts at Springwood and Lawson on Anzac Day tomorrow (Thursday), April 25.
A C-130J Hercules will fly over Springwood war memorial at 11am and Lawson cenotaph at 11.20am.
"All RAAF flypasts are subject to weather and operational requirements. For public safety, drones must not be operated in the vicinity of flypasts," said a RAAF spokesman.
From Mount Victoria to Glenbrook, Blue Mountains residents are expected to turn out in large numbers to honour our servicemen and women at Anzac Day services.
At last year's service at Glenbrook, RAAF Group Captain Karon Millett asked the crowd to think about what makes Anzac Day so special.
She talked about farmers, shopkeepers, labourers and clerks enlisting 100 years ago, who were ill-prepared for what they were about to face in Gallipoli.
In eight months, 36,000 Australian and New Zealand soldiers were killed or injured, she said.
"Imagine you were one of them living in the mud and the smell of death all around you.
"61,513 Australians died in World War I.
"Anzac Day recognises the suffering and sacrifice of the original Anzacs at Gallipoli."
At the 2018 Springwood service, Steve Tutill shared his grandfather's World War I story in the Anzac address.
Jack Tutill was shot in the arm in Gallipoli and was evacuated part of the way on Simpson's donkey until he gave up his ride halfway down the hill for a soldier who had leg injuries.
He was hanging onto the donkeys tail for the rest of the journey to the beach, said Mr Tutill.
