The 100th anniversary of the Royal Air Force's formation has been marked with a special service at St Giles Cathedral in Edinburgh.
Hundreds of guests were greeted by the RAF's Central Scotland Pipes and Drums, as serving personnel were joined by veterans during the service.
Air Marshal Julian Young, Chief of Material (Air), said: "It's lovely to see the RAF 100 celebrated across the entirety of the United Kingdom...
"So that we're able to say thank you and to celebrate this remarkable centenary year across all of the country."
But as well as remembering past achievements - the RAF has also been keen to look to its future. Special attention is being paid to training a new generation in science, technology, engineering and maths (STEM).
Air Vice Marshal Ross Paterson, Air Officer for Scotland said it's a "busy year" for the RAF.
"We're enjoying this year, its busy but already our minds are set on what the next three to four years demand.
"We're already working with partners on youth STEM, in particular, to see how we can help that in the future."
He added: "Hopefully, a lot more to come."
Services are set to take place across the UK throughout the RAF’s centenary year, to reflect on the role of the service, and to remember those who made the ultimate sacrifice along the way.
Edinburgh is also marking the anniversary year by giving its own 603 Squadron the freedom of the city.
Frank Ross, Lord Provost of Edinburgh, said: "We have a long history with the RAF in the capital going back to 1925 when 603 Squadron was first based out at Town House.
"They've been an integral part of the city life throughout that whole term."
For the hundreds who gathered at St Giles Cathedral, it was a chance to think about their own part in the RAF’s journey over the past 100 years.
